Re: faster output from php and postgres

It's probably just a slow query.

Could you print out your query in PHP to the web browser, then cut and
paste it into the psql monitor to get an explain anaylze output?

i.e.
psql dbname
#> explain analyze select .... rest of query goes here;

And give us the output of that? Thanks.
