Parameter

Name	Description
options	OptionsMetadata

Methods

commit()

public void commit()

Commits the current transaction and persists any changes to the settings (except local changes).

generatePGSettingsCte()

public String generatePGSettingsCte()

Generates a Common Table Expression that represents the pg_settings table. Note that the generated query adds two additional CTEs that could in theory hide existing user tables. It is however strongly recommended that user tables never start with 'pg_', as all system tables in PostgreSQL start with 'pg_' and 'pg_catalog' is by design always included in the search_path and is by default the first entry on the search_path. This means that user tables that start with 'pg_' always risk being hidden by user tables, unless pg_catalog has been explicitly added to the search_path after one or more user schemas.

Returns

Type	Description
String

get(String extension, String name)

public PGSetting get(String extension, String name)

Returns the current value of the specified setting.

Parameters

Name	Description
extension	String
name	String

Returns

Type	Description
PGSetting

getAll()

public List<PGSetting> getAll()

Returns all settings and their current values.

Returns

Type	Description
List<PGSetting>

getDdlTransactionMode()

public OptionsMetadata.DdlTransactionMode getDdlTransactionMode()

Returns the DdlTransactionMode that is used for this connection at this time.

Returns

Type	Description
OptionsMetadata.DdlTransactionMode

getGuessTypes()

public Set<Integer> getGuessTypes()

Returns a set of OIDs that PGAdapter should try to guess if it receives an untyped parameter value. This is needed because some clients (JDBC) deliberately send parameters without a type code to force the server to infer the type. This specifically applies to date/timestamp parameters.

Returns

Type	Description
Set<Integer>

isReplacePgCatalogTables()

public boolean isReplacePgCatalogTables()

Returns the current setting for replacing pg_catalog tables with common table expressions.

Returns

Type	Description
boolean

resetAll()

public void resetAll()

Resets all values to their 'reset' value.

rollback()

public void rollback()

Rolls back the current transaction and abandons any pending changes to the settings.

set(String extension, String name, String setting)

public void set(String extension, String name, String setting)

Sets the value of the specified setting. The new value will be persisted if the current transaction is committed. The value will be lost if the transaction is rolled back.

Parameters

Name	Description
extension	String
name	String
setting	String

setConnectionStartupValue(String extension, String name, String value)

public void setConnectionStartupValue(String extension, String name, String value)

Sets the value of the specified setting at connection startup.

Parameters

Name	Description
extension	String
name	String
value	String

setLocal(String extension, String name, String setting)

public void setLocal(String extension, String name, String setting)

Sets the value of the specified setting for the current transaction. This value is lost when the transaction is committed or rolled back.

Parameters

Name	Description
extension	String
name	String
setting	String
