Eh? I didn't mention Sql grammar. A proxy would at minimum have to
track and maintain connection settings and portals and recreate them
on each backend. However a full-featured proxy could parse any GUC
statements.
In fact if you want full support for temporary tables (iffy) /
temporary views (perhaps possible) and whatnot you will have to parse
the SQL flying across the wire so you can recreate the session in it's
entirety.
Of course, I don't want nor need that.
For the record:
Please please please note that I'm only trying to solve a particular
problem here. I know what I want to do is messy, ugly and a little
impure and flies in the face of elegant design.
If it helps think of what I'm proposing as akin to denormalization
of a beautiful schema to achieve specific goals.
