Someone isn't quoting the query string correctly on the Tcl side ---
[akID] is Tclese for command substitution.  Sounds like pgaccess expects
the user to quote command punctuation characters that should be passed
through.  Not sure if that should be regarded as a bug or a feature.
It could be considered a feature that you can enter SQL commands with
Tcl command substitution performed on them, but it's something that
would confuse non-Tcl-users a lot.

Got the message!

I'll fix the Query builder to quote []'s!
