The frontend/backend protocol does not use an architectural neutral format. For that matter, the data in the database is not stored in an architectural neutral format, either. What this means is that you cannot use client/servers with different word-sizes or different endian representation. One way to solve this problem is to change everything to a neutral format like XDR. This requires substantial code changes and some small penalty performances. We have no current plans to do this in postgres95 although it is on our (wish we had the time) TODO list. - Jolly Chen P.S. please sent postgres95 specific messages to postgres95@postgres.berkeley.edu ============================================================================== To add/remove yourself to/from the POSTGRES mailing list: send mail with the subject line ADD or DEL to "postgres-request@postgres.Berkeley.EDU".
