Hello Tatsuo & all,
Sorry: in my mast message, I meant 'double-byte forms' and not 'double_byte
unicode forms' since SP4.
In answer to your question:
Dave publish a new CVS snapshot of pgAdmin II where encodings are hard-coded.
A 'pg_available_encodings([INTEGER how]) RETURNS set of TEXT' function
would make sure users
only create a database with 'UNICODE' if PostgreSQL was built-in with
multibyte support.
A database creation time, available codings are presented in a drop-down menu.
