pgsql: Rename transformRelOptions()'s "namspace" parameter to "nameSpac

Rename transformRelOptions()'s "namspace" parameter to "nameSpace".

The name "namspace" looks like a typo, but it was presumably meant
to avoid using the "namespace" C++ keyword. This commit renames
the parameter to "nameSpace" to prevent future confusion while
still avoiding the keyword.
