map.LoadLayerOptions not working with database

As mentioned here: https://github.com/MapWindow/MapWinGIS/issues/109

I have a PostgreSQL layer successfully loaded into the OLE map control but can't load the style data stored from the mw_styles database table. The table exists and has a style record. I have turned on PostgreSQL statement logging and no mw_styles select SQL statement is being run.

My Powerbuilder code looks like this:

But LoadLayerOptions returns false.
