Check the manual. There are two ways to d othis. You could query the
data catalogs directly (something like count(*) from pg_class where
relname = $1), but this is not preferred because you have the
possibilities that the data catalogs will be changed in the future.
The better way to do this is to query the information schema. I forget
the table name but it may be something like (select count(*) from
information_schema.tables where table_name = $1). the structure of the
information schema is defined in the SQL standards and will be stable
between versions.
