pgsql: Remove redundant initialization of a local variable.

Remove redundant initialization of a local variable.

In what was doubtless a typo, commit bf6c614a2 introduced a duplicate
initialization of a local variable.  This made Coverity unhappy, as well
as pretty much anybody reading the code.  We don't even have a real use
for the local variable, so just remove it.
