I'd like to know, if it's possible, which ODBC
standard does postsgres support and where i could
find the complete text of ANSI SQL-92 and ANSI
SQL-99.
In the FAQ page i found that the maximum size for a
row? is 1.6TB and i'd like to know what exactly
they mean with "row".
Do u know about any applications realized with
Postgres and still working that i could cite to
demostrate his reliability?
Regards
Mattia Boccia

Um, the definition of "row" in a database is unambiguous. One row = One Tuple. I can't make it any clearer than that. FYI, most operating systems limit single files to 2GB or less. As such, no table -- and thus no row -- in a Postgres database running on that operating system can be larger than 2GB. But it's hard for me to imagine a row that is even 1MB, let alone 2GB, so I don't think you need to worry. > Do u know about any applications realized with > Postgres and still working that i could cite to > demostrate his reliability? See http://advocacy.postgresql.org/ I believe that their is an Italian version of that page, as well. -Josh Berkus

Josh, surely you know better than that. PG is not restricted by OS
limitations on individual file size, because it automatically segments
tables into multiple OS files.

Actually, I didn't know. When did you add that? Dammit, you programmer-types keep writing stuff too fast for me to keep up. <grin> And what on *earth* would someone store in a 3GB table? Heck, I don't think I even have a 3GB *database* in production; the 3million-record one I use in my column was only a few hundred megabytes. -Josh Berkus

AFAICT, it's been in the code since Berkeley days; Postgres 4.2 looks
to have support for it.
