Locale question

["Matthew T. O'Connor" <matthew@xxxxxxxx>]

I have a (hopefully simple) question regarding locale.

I am migrating a postgresql database from a server running FC1 & 
PostgreSQL 7.4 to a newer machine running FC2 and PostgreSQL 8.0.  I 
dumped the data from the old server using pg_dumpall and restored it to 
the new server with no problems, and while testing the new server 
everything seems to be OK.

However, I did notice that the client and server encoding settings on 
the old server are set to SQL_ASCII whereas those same settings on the 
new server are set to LATIN1.

I'm wondering if I might wind up with some lurking problems since I 
don't really understand all the implications of locale settings.

Thanks,

Matthew O'Connor
