Managed Service for PostgreSQL API, REST: User.Update

Field

Description

clusterId

string

Required field. ID of the PostgreSQL cluster the user belongs to.
To get the cluster ID use a ClusterService.List request.

userName

string

Required field. Name of the user to be updated.
To get the name of the user use a UserService.List request.

Field

Description

updateMask

object (field-mask)

A comma-separated names off ALL fields to be updated.
Only the specified fields will be changed. The others will be left untouched.
If the field is specified in updateMask and no value for that field was sent in the request,
the field's value will be reset to the default. The default value for most fields is null or 0.

If updateMask is not sent in the request, all fields' values will be updated.
Fields specified in the request will be updated to provided values.
The rest of the fields will be reset to the default.

password

string

New password for the user.

permissions[]

Permission

Set of permissions granted to the user to access specific databases.

connLimit

string (int64)

Maximum number of database connections available to the user.

When used in session pooling, this setting limits the number of connections to every single host in PostgreSQL cluster. In this case, the setting's value must be greater than the total number of connections that backend services can open to access the PostgreSQL cluster. The setting's value should not exceed the value of the [Cluster.config.postgresql_config.max_connections] setting.

When used in transaction pooling, this setting limits the number of user's active transactions; therefore, in this mode user can open thousands of connections, but only N concurrent connections will be opened, where N is the value of the setting.

Minimum value: 10 (default: 50), when used in session pooling.

settings

UserSettings

login

boolean

This flag defines whether the user can login to a PostgreSQL database.

Default value: true (login is allowed).

grants[]

string

A set of roles and privileges that are granted to the user.

For more information, see the documentation.

deletionProtection

boolean

Deletion Protection inhibits deletion of the user

Default value: unspecified (inherits cluster's deletion_protection)

userPasswordEncryption

enum (UserPasswordEncryption)

New password-based authentication method for user.
Possible values are USER_PASSWORD_ENCRYPTION_MD5 or USER_PASSWORD_ENCRYPTION_SCRAM_SHA_256.

• USER_PASSWORD_ENCRYPTION_UNSPECIFIED
• USER_PASSWORD_ENCRYPTION_MD5
• USER_PASSWORD_ENCRYPTION_SCRAM_SHA_256

Field

Description

databaseName

string

Name of the database that the permission grants access to.

Field

Description

defaultTransactionIsolation

enum (TransactionIsolation)

SQL sets an isolation level for each transaction.
This setting defines the default isolation level to be set for all new SQL transactions.

For more information, see the PostgreSQL documentation.

• TRANSACTION_ISOLATION_UNSPECIFIED
• TRANSACTION_ISOLATION_READ_UNCOMMITTED: This level behaves like TRANSACTION_ISOLATION_READ_COMMITTED in PostgreSQL.
• TRANSACTION_ISOLATION_READ_COMMITTED: On this level query sees only data committed before the query began. Default value.
• TRANSACTION_ISOLATION_REPEATABLE_READ: On this level all subsequent queries in a transaction will see the same rows, that were read by the first SELECT or INSERT query in this transaction, unchanged (these rows are locked during the first query).
• TRANSACTION_ISOLATION_SERIALIZABLE: This level provides the strictest transaction isolation.
  All queries in the current transaction see only the rows that were fixed prior to execution of the first SELECT or INSERT query in this transaction.
  If read and write operations in a concurrent set of serializable transactions overlap and this may cause an inconsistency that is not possible during the serial transaction execution, then one of the transaction will be rolled back, triggering a serialization failure.

lockTimeout

string (int64)

The maximum time (in milliseconds) for any statement to wait for acquiring a lock on an table, index, row or other database object.
If the wait time is longer than the specified amount, then this statement is aborted.

Default value: 0 (no control is enforced, a statement waiting time is unlimited).

logMinDurationStatement

string (int64)

This setting controls logging of the duration of statements.

The duration of each completed statement will be logged if the statement ran for at least the specified amount of time (in milliseconds).
E.g., if this setting's value is set to 500, a statement that took 300 milliseconds to complete will not be logged; on the other hand, the one that took 2000 milliseconds to complete, will be logged.

Value of 0 forces PostgreSQL to log the duration of all statements.

Value of -1 (default) disables logging of the duration of statements.

For more information, see the PostgreSQL documentation.

synchronousCommit

enum (SynchronousCommit)

This setting defines whether DBMS will commit transaction in a synchronous way.

When synchronization is enabled, cluster waits for the synchronous operations to be completed prior to reporting success to the client.
These operations guarantee different levels of the data safety and visibility in the cluster.

For more information, see the PostgreSQL documentation.

• SYNCHRONOUS_COMMIT_UNSPECIFIED
• SYNCHRONOUS_COMMIT_ON: Success is reported to the client if the data is in WAL (Write-Ahead Log), and WAL is written to the storage of both the master and its synchronous standby server. Default value.
• SYNCHRONOUS_COMMIT_OFF: Success is reported to the client even if the data is not in WAL.
  There is no synchronous write operation, data may be loss in case of storage subsystem failure.
• SYNCHRONOUS_COMMIT_LOCAL: Success is reported to the client if the data is in WAL, and WAL is written to the storage of the master server.
  The transaction may be lost due to storage subsystem failure on the master server.
• SYNCHRONOUS_COMMIT_REMOTE_WRITE: Success is reported to the client if the data is in WAL, WAL is written to the storage of the master server, and the server's synchronous standby indicates that it has received WAL and written it out to its operating system.
  The transaction may be lost due to simultaneous storage subsystem failure on the master and operating system's failure on the synchronous standby.
• SYNCHRONOUS_COMMIT_REMOTE_APPLY: Success is reported to the client if the data is in WAL (Write-Ahead Log), WAL is written to the storage of the master server, and its synchronous standby indicates that it has received WAL and applied it.
  The transaction may be lost due to irrecoverably failure of both the master and its synchronous standby.

tempFileLimit

string (int64)

The maximum storage space size (in kilobytes) that a single process can use to create temporary files.
If a transaction exceeds this limit during execution, it will be aborted.

A huge query may not fit into a server's RAM, therefore PostgreSQL will use some storage to store and execute such a query. Too big queries can make excessive use of the storage system, effectively making other quieries to run slow. This setting prevents execution of a big queries that can influence other queries by limiting size of temporary files.

logStatement

enum (LogStatement)

This setting specifies which SQL statements should be logged (on the user level).

For more information, see the PostgreSQL documentation.

• LOG_STATEMENT_UNSPECIFIED
• LOG_STATEMENT_NONE: Logs none of SQL statements. Default value.
• LOG_STATEMENT_DDL: Logs all data definition statements (such as CREATE, ALTER, DROP and others).
• LOG_STATEMENT_MOD: Logs all statements that fall in the LOG_STATEMENT_DDL category plus data-modifying statements (such as INSERT, UPDATE and others).
• LOG_STATEMENT_ALL: Logs all SQL statements.

poolMode

enum (PoolingMode)

Mode that the connection pooler is working in with specified user.

For more information, see the Odyssey documentation.

• POOLING_MODE_UNSPECIFIED
• SESSION: Server connection will be assigned to it for the whole duration the client stays connected. Default value.
• TRANSACTION: Server connection is assigned to a client only during a transaction.
• STATEMENT: Server connection will be put back into the pool immediately after a query completes.

preparedStatementsPooling

boolean

User can use prepared statements with transaction pooling.

For more information, see the PostgreSQL documentation.

catchupTimeout

string (int64)

The connection pooler setting. It determines the maximum allowed replication lag (in seconds).
Pooler will reject connections to the replica with a lag above this threshold.
It can be useful to prevent application from reading stale data.

Default value: 0

Value of 0 disables this mechanism

walSenderTimeout

string (int64)

The maximum time (in milliseconds) to wait for WAL replication (can be set only for PostgreSQL 12+)
Terminate replication connections that are inactive for longer than this amount of time.

Default value: 60000 (60 seconds).

Value of 0 disables the timeout mechanism.

For more information, see the PostgreSQL documentation.

idleInTransactionSessionTimeout

string (int64)

Sets the maximum allowed idle time, in milliseconds, between queries while in a transaction.

The default value is 0, which disables the timeout.

For more information, see the PostgreSQL documentation.

statementTimeout

string (int64)

The maximum time (in milliseconds) to wait for statement.
The timeout is measured from the time a command arrives at the server until it is completed by the server.

If log_min_error_statement is set to ERROR or lower, the statement that timed out will also be logged.

Value of 0 (default) disables the timeout

For more information, see the PostgreSQL documentation.

pgaudit

• PG_AUDIT_SETTINGS_LOG_FUNCTION: Function invocations and DO sections are logged.
• PG_AUDIT_SETTINGS_LOG_ROLE: Statements related to role and privilege management, such as GRANT, REVOKE, or CREATE/ALTER/DROP ROLE, are logged.
• PG_AUDIT_SETTINGS_LOG_DDL: Any DDL statements that do not belong to the ROLE class are logged.
• PG_AUDIT_SETTINGS_LOG_MISC: Miscellaneous commands, such as DISCARD, FETCH, CHECKPOINT, VACUUM, and SET, are logged.
• PG_AUDIT_SETTINGS_LOG_MISC_SET: Miscellaneous SET commands, e.g., SET ROLE, are logged.

The default value is PG_AUDIT_SETTINGS_LOG_UNSPECIFIED. In this case, the parameter is not configured.
