I think your php client must be connecting to a different database
than you are connecting to when you run psql by hand. If you are
allowing the default choice of database name = user name to be taken,
this isn't real surprising...

"relation" and "table" are more or less synonymous in PG error messages.
(IMHO the exact meaning of "relation" in our code is "something with a
pg_class entry", which covers also views, sequences, indexes, etc; but
you probably didn't need to know that.)
