The command I used is: > CREATE INDEX CONCURRENTLY test_schema_notes_trigram_idx on > test_schema.notes USING gin (notes gin_trgm_ops); Well, the first question is whether the index building session is actually doing anything or just waiting. Is it consuming CPU time? It might just be waiting around for some other transaction to finish --- there are multiple places in a CREATE INDEX CONCURRENTLY sequence where we have to wait out all other open transactions. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
