Bartek, Thanks. The reason I use the cursor is that I want to check the table
is in the pg_tables or not,
If it exists, the function will execute successfully, if not, it will raise
the message that the table doesn't exist. For the schema part, I assume the
people has set the search_path to that schema which the table is in and
because our database only has one schema. So I assume they have the right
search_path.
Thanks for your advice. It helps me a lot.
