Thanks for responding Magnus. I did reinstall both msys and mingw, as well as blow away the source and start over from scratch. Maybe there is a stray file or directory that's not getting deleted on the clean. Also, does clean just clean up the compile environment, or does it also clean up the install? I did manually remove directories too but I suppose I could have missed something. Out of desperation, I decided to try everything on my wife's mac, remembering that os x is unix. Didn't take long at all to download all the dev tools I needed, get a clean compile and get things running there. Can't remember if it was in this forum, but a few people asked why I was downloading source and not binary - I am experimenting with a different indexing (multi-dimensional) method. I looked hard at GiST, but it doesn't look like GiST supports multi-dimensional indexing methods unless all the dimensions are in a single column. I need to see each column in the index before making a decision about search paths to take, branches to follow, etc. GiST appears to support one column at a time - i.e. if my index is lastname, firstname, then take a look at lastname, and if that's a tie, then look at firstname. But it won't let you look at lastname and firstname at the same time, then make decisions. Other than that, looks like an outstanding feature. Finally, as a newcomer to PG, I'm in search of general development resources. Any good places to go besides the PG documentation and the pgsql newsgroups? Regards, Eric
