Question

I need to find all the visible tables in my current schema search path. I tried:

SELECT *
FROM pg_tables
AND schemaname IN (SHOW search_path)

but it errors with:

PGError: ERROR: syntax error at or near "search_path"
LINE 3: AND schemaname IN (SHOW search_path)

Answer 1

The pg_*_is_visible() set of functions is provided for this purpose. Here is one way to use them:

SELECT * FROM pg_class WHERE relkind IN ('r', 'v') AND pg_table_is_visible(oid);
