Subject: Use more appropriate DatumGet* function
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=8c6bbd674ed810df9af5ec42f6b38c205e3ad365;p=postgresql.git

Use more appropriate DatumGet* function

Use DatumGetCString() instead of DatumGetPointer() for returning a C
string.  Right now, they are the same, but that doesn't always have to
be so.
