Re: temp table existence

["Pavel Stehule" <pavel(dot)stehule(at)gmail(dot)com>]

Hello

my solution isn't 100% perfect too. Better is test visibility:

SELECT n.nspname as "Schema",
  c.relname as "Name",
  CASE c.relkind WHEN 'r' THEN 'table' WHEN 'v' THEN 'view' WHEN 'i'
THEN 'index' WHEN 'S' THEN 'sequence' WHEN 's' THEN 'special' END as
"Type",
  r.rolname as "Owner"
FROM pg_catalog.pg_class c
     JOIN pg_catalog.pg_roles r ON r.oid = c.relowner
     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind IN ('r','')
  AND n.nspname <> 'pg_catalog' -- replace LIKE 'pg_temp%';
  AND n.nspname !~ '^pg_toast'
  AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 1,2;

for existence test this query can be simplified
