Subject: bdr, deparse: Deparse nondefault seqams correctly when default_seqam is set.
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=refs%2Fheads%2Fbdr-next;p=users%2Fandresfreund%2Fpostgres.git

bdr, deparse: Deparse nondefault seqams correctly when default_seqam is set.

This could lead to sequences being created as bdr sequences on one
node and local sequences on others.
