Subject: Tweak pg_dumpall to add GRANT CONNECT ON DATABASE ... TO PUBLIC when dumping
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=eaf193ea4439b3dedbcc04af1dab6832d3ad0fc7;p=users%2Fbernd%2Fpostgres.git

Tweak pg_dumpall to add GRANT CONNECT ON DATABASE ... TO PUBLIC when dumping
database privileges from a pre-8.2 server.  This ensures that the reloaded
database will maintain the same behavior it had in the previous installation,
ie, everybody has connect privilege.  Per gripe from L Bayuk.
