Yet another problem with Turkish encoding. clean_encoding_name()
in src/backend/utils/mb/encnames.c uses tolower() to convert locale

Hello
In PostgreSQL 7.2/7.1:
template1=# select text(2.000::numeric);
text
--
2
(1 row)
In 7.3:
template1=# select text(2.000::numeric);
text
---
2.000
(1 row)
The text(numeric) function doesn't round numbers. :(
This is bug or feature? :)
I wonder if the sequences created by SERIAL should not be going into a
pg_sequence schema and protected like the toast tables are.
One could still share sequences by explicitly creating them and using a
DEFAULT clause with nextval().
We could even stop printing that annoying NOTICE ;-)
I've been getting reports of one of my test scenarios for libpqxx
failing with postgres 7.3. At the moment I can't reproduce this (I'm
still on 7.2) and I can't find anything pertinent in CVS commit

this list.
