Subject: Fix dumping of DEFERRABLE/INITIALLY DEFERRED:
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=524333e8aa3438af16b64cd12d6fc913e3d235df;p=users%2Fbernd%2Fpostgres.git

Fix dumping of DEFERRABLE/INITIALLY DEFERRED:

> The big problem is that while pg_dump's dump_trigger() looks at

pg_get_constraintdef should probably be looking at condeferrable and
condeferred in the pg_constraint row it's looking at.  Maybe something
like the attached.

(Added, output only non-default values.)
