Subject: If RelationBuildDesc() fails to open a critical system index, PANIC with
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=58e8f77efb4ee180299444d4ae2a9034c63cea7c;p=users%2Fbernd%2Fpostgres.git

If RelationBuildDesc() fails to open a critical system index, PANIC with
a relevant error message instead of just dumping core.  Odd that nobody
reported this before Darren Reed.
