Description
bool pg_trace (string
filename [, string
mode [, int
connection]])
Enables tracing of the PostgreSQL frontend/backend communication
to a debugging file. To fully understand the results one needs to be
familiar with the internals of PostgreSQL communication protocol.
For those who are not, it can still be useful for tracing errors in
queries sent to the server, you could do for example
'grep '^To backend' trace.log' and see what queriew actually were sent
to the PostgreSQL server.
filename and mode are the
same as in fopen() (mode defaults
to 'w'), connection specifies the connection to
trace and defaults to the last one opened.
Returns TRUE if filename could be opened for
logging, FALSE otherwise.
See also fopen() and pg_untrace().
