Comments from a Firebird user via Borland Newsgroups.

<We found PostgreSQL a mature product, but in two things Firebird was 
simply better than PostgreSQL: Two-Phase commit (ok, that is gone with 
PG 8.1), but the second is a SNAPSHOT / REPEATABLE READ transaction 
isolation. I can't live without that when it comes having a stable view 
of data during one transaction, or did that change with 8.1? Is there 
now a SNAPHOST / REPEATBLE READ transaction isolation level available as 
well?>

Just wondering what the PG take on this snapshot repeatable read stuff is.
