(PHP 5 >= 5.1.0)
pg_set_error_verbosity — Determines the verbosity of messages returned by pg_last_error() and pg_result_error().
说明 int pg_set_error_verbosity ([ resource $connection ], int $verbosity )Determines the verbosity of messages returned by pg_last_error() and pg_result_error().
pg_set_error_verbosity() sets the verbosity mode, returning the connection&#;s previous setting. In PGSQL_ERRORS_TERSE mode, returned messages include severity, primary text, and position only; this will normally fit on a single line. The default mode (PGSQL_ERRORS_DEFAULT) produces messages that include the above plus any detail, hint, or context fields (these may span multiple lines). The PGSQL_ERRORS_VERBOSE mode includes all available fields. Changing the verbosity does not affect the messages available from already-existing result objects, only subsequently-created ones.
参数connection 
PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().
verbosityThe required verbosity: PGSQL_ERRORS_TERSE, PGSQL_ERRORS_DEFAULT or PGSQL_ERRORS_VERBOSE.
返回值The previous verbosity level: PGSQL_ERRORS_TERSE, PGSQL_ERRORS_DEFAULT or PGSQL_ERRORS_VERBOSE.
