Hi - I ran into the problem that the notices that are sent from the postgres backend
are being ignored by php. Most of the time this doesn't matter, but it would be nice
to be able to profile an application by running explains (which show sql cost) on
every sql statement that is executed that way you can find where your problems are as
you develop the software. Below is a patch to add this php4 (Although I don't have a
cvs I account - I did built it against the 200103031945 snap shot so it should be easy
to integrate into the source tree) Can you please add this before the next release :)
new php function - I wasn't sure how to document this in the code so here is is in the
bug report
pg_last_notice(int connection)
returns either an empty string or the contents of the last notice sent out by the
database.
This can be useful to get the output from the explain command.
see patch below
