I tried sometime ago ... but with no responses, I ask you again. pg_publication_tables is a view that is used to refresh publication, but as we have 15.000 tables, it takes hours and doesn´t complete. If I change that view I can have an immediate result. The question is: Can I change that view ? There is some trouble changing those system views ? Original View is ... create view pg_catalog.pg_publication_tables as SELECT p.pubname, n.nspname AS schemaname, c.relname AS tablename FROM pg_publication p, (pg_class c JOIN pg_namespace n ON ((n.oid = c.relnamespace))) WHERE (c.oid IN (SELECT pg_get_publication_tables.relid FROM pg_get_publication_tables((p.pubname)::text) pg_get_publication_tables(relid))); This way it takes 45 minutes to respond. I changed it to ... create or replace pg_catalog.view pg_publication_tables as SELECT p.pubname, n.nspname AS schemaname, c.relname AS tablename from pg_publication p inner join pg_get_publication_tables(p.pubname) pt on true inner join pg_class c on pt.relid = c.oid inner join pg_namespace n ON (n.oid = c.relnamespace); This one takes just one or two seconds. -- Sent from: http://www.postgresql-archive.org/PostgreSQL-general-f1843780.html
