Dear list members, maybe a naive question but I was unable to find an answer in the fine manual (sv_SE being an example) Does running DROP COLLATION IF EXISTS pg_catalog."sv_SE" also remove the corresponding row from pg_collation (assuming nothing depends on collation sv_SE) ? Experimentation seems to hint that way but I was unable to confirm. Thanks Karsten -- GPG 40BE 5B0E C98E 1713 AFA6 5BC0 3BEA AC80 7D4F C89B
