I have added SQL99's CONVERT() function. docs and regression tests
also updated. Our own convert() functions can also be used. Example
usage of CONVERT():
convert('PostgreSQL' using iso8859_1_to_utf8)
will return 'PostgreSQL' in UTF-8 encoding. See "String Functions and
Operators" section of Users's guide for more details and currently
available (predefined) conversions.
I believe remaining work for CONVERSION stuffs is some conversions for
cyrillic and win874/1250/1251/1256 encodings.
