Deprecated Interfaces

Interface and Description
org.postgresql.PGRefCursorResultSet As of 8.0, this interface is only present for backwards- compatibility purposes. New code should call getString() on the ResultSet that contains the refcursor to obtain the underlying cursor name.

Deprecated Classes

Class and Description
org.postgresql.jdbc2.optional.ConnectionPool Please use PGConnectionPoolDataSource
org.postgresql.jdbc.EscapedFunctions see EscapedFunctions2
org.postgresql.fastpath.Fastpath This API is somewhat obsolete, as one may achieve similar performance and greater functionality by setting up a prepared statement to define the function call. Then, executing the statement with binary transmission of parameters and results substitutes for a fast-path function call.
org.postgresql.fastpath.FastpathArg This API is somewhat obsolete, as one may achieve similar performance and greater functionality by setting up a prepared statement to define the function call. Then, executing the statement with binary transmission of parameters and results substitutes for a fast-path function call.
org.postgresql.jdbc3.Jdbc3ConnectionPool Please use PGConnectionPoolDataSource
org.postgresql.jdbc3.Jdbc3PoolingDataSource Since 42.0.0, see PGPoolingDataSource
org.postgresql.jdbc3.Jdbc3SimpleDataSource Please use PGSimpleDataSource
org.postgresql.ssl.jdbc4.LibPQFactory prefer LibPQFactory
org.postgresql.ds.PGPoolingDataSource Since 42.0.0, instead of this class you should use a fully featured connection pool like HikariCP, vibur-dbcp, commons-dbcp, c3p0, etc.
org.postgresql.jdbc2.optional.PoolingDataSource Since 42.0.0, see PGPoolingDataSource
org.postgresql.jdbc2.optional.SimpleDataSource Please use PGSimpleDataSource

Deprecated Fields

Field and Description
org.postgresql.core.QueryExecutor.QUERY_DISALLOW_BATCHING in PgJDBC 9.4 as we now auto-size batches.

Deprecated Methods

Method and Description
org.postgresql.PGConnection.addDataType(String, String) As of 8.0, replaced by PGConnection.addDataType(String, Class). This deprecated method does not work correctly for registering classes that cannot be directly loaded by the JDBC driver's classloader.
org.postgresql.largeobject.LargeObjectManager.create() As of 8.3, replaced by LargeObjectManager.createLO()
org.postgresql.largeobject.LargeObjectManager.create(int) As of 8.3, replaced by LargeObjectManager.createLO(int)
org.postgresql.core.QueryExecutor.createFastpathParameters(int) This API is somewhat obsolete, as one may achieve similar performance and greater functionality by setting up a prepared statement to define the function call. Then, executing the statement with binary transmission of parameters and results substitutes for a fast-path function call.
org.postgresql.largeobject.LargeObjectManager.delete(int) As of 8.3, replaced by LargeObjectManager.delete(long)
org.postgresql.fastpath.Fastpath.fastpath(int, boolean, FastpathArg[]) please use Fastpath.fastpath(int, FastpathArg[])
org.postgresql.fastpath.Fastpath.fastpath(String, boolean, FastpathArg[]) Use Fastpath.getData(String, FastpathArg[]) if you expect a binary result, or one of Fastpath.getInteger(String, FastpathArg[]) or Fastpath.getLong(String, FastpathArg[]) if you expect a numeric one
org.postgresql.core.QueryExecutor.fastpathCall(int, ParameterList, boolean) This API is somewhat obsolete, as one may achieve similar performance and greater functionality by setting up a prepared statement to define the function call. Then, executing the statement with binary transmission of parameters and results substitutes for a fast-path function call.
org.postgresql.PGConnection.getFastpathAPI() This API is somewhat obsolete, as one may achieve similar performance and greater functionality by setting up a prepared statement to define the function call. Then, executing the statement with binary transmission of parameters and results substitutes for a fast-path function call.
org.postgresql.largeobject.LargeObject.getOID() As of 8.3, replaced by LargeObject.getLongOID()
org.postgresql.PGRefCursorResultSet.getRefCursor() As of 8.0, replaced with calling getString() on the ResultSet that this ResultSet was obtained from.
org.postgresql.Driver.getVersion() use Driver.getMajorVersion() and Driver.getMinorVersion() instead
org.postgresql.largeobject.LargeObjectManager.open(int) As of 8.3, replaced by LargeObjectManager.open(long)
org.postgresql.largeobject.LargeObjectManager.open(int, int) As of 8.3, replaced by LargeObjectManager.open(long, int)
org.postgresql.core.Utils.parseServerVersionStr(String) use specific Version instance
org.postgresql.PGStatement.setUseServerPrepare(boolean) As of build 302, replaced by PGStatement.setPrepareThreshold(int)
org.postgresql.largeobject.LargeObjectManager.unlink(int) As of 8.3, replaced by LargeObjectManager.unlink(long)
org.postgresql.ssl.jdbc4.LibPQFactory.verify(String, SSLSession) use PgjdbcHostnameVerifier
org.postgresql.ssl.jdbc4.LibPQFactory.verifyHostName(String, String) use PGjdbcHostnameVerifier

Deprecated Constructors

Constructor and Description
org.postgresql.ssl.jdbc4.LibPQFactory(Properties) prefer LibPQFactory
org.postgresql.core.PGStream(SocketFactory, HostSpec) use PGStream.PGStream(SocketFactory, org.postgresql.util.HostSpec, int)

Deprecated Enum Constants

Enum Constant and Description
org.postgresql.PGProperty.SOCKET_FACTORY_ARG use ..Factory(Properties) constructor.
org.postgresql.PGProperty.SSL_FACTORY_ARG use ..Factory(Properties) constructor.
