These functions control miscellaneous details of libpq 's behavior.
PQsetErrorVerbosity
Determines the verbosity of messages returned by
PQerrorMessage
and
PQresultErrorMessage
.
typedef enum { PQERRORS_TERSE, PQERRORS_DEFAULT, PQERRORS_VERBOSE } PGVerbosity; PGVerbosity PQsetErrorVerbosity(PGconn *conn, PGVerbosity verbosity);
PQsetErrorVerbosity
sets the verbosity mode, returning the connection's previous setting. In
TERSE
mode, returned messages include severity, primary text, and position only; this will normally fit on a single line. The default mode produces messages that include the above plus any detail, hint, or context fields (these may span multiple lines). The
VERBOSE
mode includes all available fields. Changing the verbosity does not affect the messages available from already-existing
PGresult
objects, only subsequently-created ones.
PQtrace
Enables tracing of the client/server communication to a debugging file stream.
void PQtrace(PGconn *conn, FILE *stream);
Note: On Windows, if the libpq library and an application are compiled with different flags, this function call will crash the application because the internal representation of the FILE pointers differ. Specifically, multithreaded/single-threaded, release/debug, and static/dynamic flags should be the same for the library and all applications using that library.
PQuntrace
Disables tracing started by
PQtrace
.
void PQuntrace(PGconn *conn);
