A friend asked me to figure out how to access PostgreSQL from Tcl via ODBC. For posterity, here's the step by step "how I did it" that I emailed to him. I don't know Tcl, this was just about getting the compile options correct and doing the proper sysadminning to make things work. Comments, suggestions and clarifications appreciated, hopefully this will save the next person going through the pain a few steps: http://www.flutterby.com/archives/2001_Feb/19_PostgreSQLfromTclwithODBC.html
