Обсуждение: How can I check whether a table is existing or not

I am using Perl/DBI and I want to know whether I can check if a certain
table is in the database or not.
How can I do that without getting "ugly" messages on STDERR?

You can query the system catalogs for the relation you are interested
in; The following query might help:

SELECT c.relname FROM pg_class c WHERE c.relname = 'my_table';

where my_table is the name of the table you are looking for.
