Exactly, that is it... I reconstructed manually off my ERD from
PostgreSQL but always worried that I will miss something, etc
Don't get me wrong though, I love that someone/s (sic) has made these
drivers in the first instance, much appreciated...

And THAT is the main beauty, for me at least, of having the FK /
relationships emulated in the Access front end, in the GUI Query
Builder... whatever you say about Access, that IMHO is a sweet, sweet
feature...

|Cute ... but well ... you know ;)
In my experience, not huge, Access can get a little 'confused' when
running queries if there is a FK that is not emulated in the
relationship ERD (sic) in Access...

Yep, went through and drew them - but worried I missed some AND when I
change my design I need to remember to propagate those changes 'down the
line'... (interesting to see how Access handles those multiple links...)
Shall I come over and unplug your telly? You can miss East Enders one
weekend? GDR
