pgsql/ /configure.in oc/src/sgml/installation. ...

- PostgreSQL requires to be compiled with --enable-multibyte
and --enable-unicode-convertion if it ought to work correctly
with Tcl/Tk >= 8.1 (client or server side).

- PL/Tcl needs to be changed to use pg_do_encoding_conversion
if it runs on a Tcl version >= 8.1 .

I'll do pl/tcl part in the next version of patch. Using this approach we
can eliminate overhead for databases in UNICODE.

Any progress on this? I'd prefer to get rid of this --enable-pltcl-utf
option before release.

Done

Next version removes --enable-pltcl-utf switch and enables embedded
utf conversion of pgsql if tcl version >=8.1 and --enable-unicode-conversion
