Re: PG 9.4.4 issue on French Windows 32 bits - Mailing list pgsql-general

There is NO problem on 64 bits machines with PG 64 bits.
(We have not try PG 32 bits on 64 bits machine.)
There IS problem on all 32 bits machine with PG 32 bits

All databases are encoded on PG in UTF8

We set that on all connexions :
SET CLIENT_ENCODING TO WIN1252;
SET bytea_output TO escape;
SET standard_conforming_strings TO false;

I don't use psql. So i don't anderstand when i must type  "\encoding
win1252".
if i use psql on the test 9.4.4 database and type "\encoding win1252",
nothing happens
If then i try a simple query updating string with "\\", value is stored
If i do same thing with some accentuated char : "\\éà", there are NOT
updated in database, and no error (and nothing in PG log)
If i do that from PG_Admin, it works
If i type "SET CLIENT_ENCODING TO WIN1252;", psql return error : invalid
byte sequence for encoding "UTF8": 0xe9 0x71 0x75
If i do that from PG_Admin, it works
If i type "SET CLIENT_ENCODING TO WIN1252"  (without ";"), it works

I don't see any coherent things !  :(

Thanks,
