pg_encoding_to_char
---------------------
SQL_ASCII
(1 row)
The 7.2 system was compiled without multibyte support. In 7.3, multibyte
is always on. I guess it probably doesn't matter much as it's obviously
giving only useful encodings, the problem is this (on the 7.2 system):
template1=> select pg_encoding_to_char(45);
pg_encoding_to_char
---------------------
SQL_ASCII
(1 row)
template1=> select pg_encoding_to_char(450);
pg_encoding_to_char
---------------------
SQL_ASCII
(1 row)
How would the loop know when to give up and exit?
Regards, Dave.

I replace this code in frmdatabase pgadmin2. I don't have this
problem.
What is your result if you execute this selection ?
select pg_encoding_to_char(0)
union select pg_encoding_to_char(1)
union select pg_encoding_to_char(2)
union select pg_encoding_to_char(3)
union select pg_encoding_to_char(4)
union select pg_encoding_to_char(5)
union select pg_encoding_to_char(6)
union select pg_encoding_to_char(7)
union select pg_encoding_to_char(8)
union select pg_encoding_to_char(9)
union select pg_encoding_to_char(10)
union select pg_encoding_to_char(11)
union select pg_encoding_to_char(12)
union select pg_encoding_to_char(13)
union select pg_encoding_to_char(14)
union select pg_encoding_to_char(15)
union select pg_encod! ing_to_ch a r(16)
union select pg_encoding_to_char(17)
union select pg_encoding_to_char(18)
union select pg_encoding_to_char(19)
union select pg_encoding_to_char(20)
union select pg_encoding_to_char(21)
My result is :
pg_encoding_to_char

The order is not by number encoding.
Hi Frank,
Hmm, that doesn't seem to work here. For any random
integervalue of X that I try in select pg_encoding_to_char(X), I get
SQL_ASCII as the result.
This is a problem I would like to fix, though I don't
have time myself right now :-(
Regards, Dave.

For reading automatly encodign usign this
code : < /P>
