Thread: pgsql: Suppress compiler warning in pub_collist_to_bitmapset().

Suppress compiler warning in pub_collist_to_bitmapset().

A fair percentage of the buildfarm doesn't recognize that oldcxt
won't be used uninitialized; silence those warnings by initializing it.

While here, upgrade the function's thoroughly inadequate header comment.

Oversight in 923def9a5, per buildfarm.
