Connect to database with php pg_connect, cannot find table even though it shows up on psql connection

Hi gang,

I have a database named fubar. That database has a table named
do_s. I run a php command
pg_connect(" host=myHost user=myUsername password=myPassword
dbname=fubar")
which executes successfully. When I run a postgresql command
against do_s I am told the relation does not exist.
When I connect using psql I can find the table with no problem. The
table is in the public schema. It was not created with capital letters
in its name. Looking for public.do_s does not help.

I would like to know a postgresql command which tells me the name of
the database I am connected to.

I suspect the system is doing something funny and have contacted
our sysadmin people, who are doing all kinds of things to our network as
a result of our being hacked a couple of weeks ago. But it would help
to know the name of the database I actually connected to!

Thanks

Mary Anderson
