Hi,
as far as I've found out, it doesn't.
Retrieving int data as hex I solved by this plperl function:
CREATE FUNCTION int2hex(integer) RETURNS char(10)
AS '$tmp = sprintf "%X", $_[0];
return ("0x" . "0"x(4-length($tmp)) . $tmp);'
LANGUAGE 'plperl';
This will give you allways 4 ciphers behind 0x. I didn't need it for
reading data, but at least, it should work about the same, i.e. if you have
several kinds of numbers, some dec, some hex, some oct, I would do
something like:
CREATE FUNCITON mynumber2int(char(10)) RETURNS integer
AS 'return int($_[0]);'
LANGUAGE 'plperl';
which simply uses perls internal conversion-mechanism.
I would also like postgres to include this behavior by default, at least
for the reading. But I haven't found out how.
