database via builtin functions, as recently discussed on -hackers. chr() now returns a character in the database encoding. For UTF8 encoded databases the argument is treated as a Unicode code point. For other multi-byte encodings the argument must designate a strict ascii character, or an error is raised, as is also the case if the argument is 0. ascii() is adjusted so that it remains the inverse of chr(). The two argument form of convert() is gone, and the three argument form now takes a bytea first argument and returns a bytea. To cover this loss three new functions are introduced: . convert_from(bytea, name) returns text - converts the first argument from the named encoding to the database encoding . convert_to(text, name) returns bytea - converts the first argument from the database encoding to the named encoding . length(bytea, name) returns int - gives the length of the first argument in characters in the named encoding |
