int pg_set_error_verbosity ( resource connection, int verbosity )
int pg_set_error_verbosity Determines the verbosity of messages returned by and .
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.
