Subject: Replace strdup() with pstrdup(), to avoid leaking memory.
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=4919a20c3331dbecd170387b58075210d6245f51;p=users%2Fc2main%2Fpostgres.git

Replace strdup() with pstrdup(), to avoid leaking memory.

It's been like this since the seg module was introduced, so backpatch to
8.2 which is the oldest supported version.
