But the question popped up whether PostgreSQL can be extended
to allow localized literals and apply encoding conversion the same
way as on string data. NAMEDATA can be replaced with regular TEXT
and have the same conversion everywhere. This way the relation and
field name limits are also eliminated. The conversion could be controlled
by a compile-time option and/or a GUC variable. Tell me if I am crazy.

It does convert the table names also, since the encoding translation is
applied to the whole query string, not just normal strings.

Thanks for enlightenment, I didn't know or check it.

 A simple
SET CLIENT_ENCODING='latin9' at the beginning of your dump should have
worked.

I thought so - the dump was off a 7.4 server with its pg_dump
and there was no "SET client_encoding = ..." in the script.
They insisted on continuing with LATIN9 but with the default
UTF-8 server encoding createdb -E LATIN9 failed.

As for the other point, the reason NAMEDATA is fixed is because these
records is mapped onto in memory structures in the backend. By changing
it to a variable length type all structure accesses would become much
more expensive.

Yes, I guessed it would be slower. However, NAMEDATALEN
doesn't translate to the varchar(NAMEDATALEN) if I use accented
characters in literals with UTF-8 encoding. :-(

But none of this has anything ot do with encodings.

Have a nice day,

Thanks, I have it. :-)
