X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=59f237f7302542e5eb5e6683cb78d62ef5279261;p=users%2Fbernd%2Fpostgres.git

a relevant error message instead of just dumping core.  Odd that nobody
reported this before Darren Reed.
