pg_restore new option -m
ohp@pyrenet.fr — 2009-02-18T17:55:53Z
hi, i've been testing new -m option of pg_restore with great pleasure. first, let me thank the developpers, it cut restoring time by half. is it normal that -m doesn't cope well with -C? createdb db pg_restore -m 4 -d db db.dmp works like a charm while pg_restore -C -m 4 -d template1 db.dmp gives numerous errors, mostly no such relation at index creation time.

It's because we reconnect to the wrong db in this case (i.e. to the -d database, not the created one) in the workers and subsequent connects. I've applied a trivial patch to fix it. cheers andrew
