same new code

here is function to get client ip address (only ipv4),
server address, and fe/be ports , details inside
http://www.psycho.pl/public/src/pgsql/ivnet.tar.bz2

please test it in yours systems (i tested on Debian 2.4.21 with grsec.)

2. Whats up with PG_RETURN_UINT16 ??
and with type uintXX ?

And why do you writing a block of code in do { ... } while(0) ?
i thing that { ... } will be this same (whitout 'while') (????)

And only types with length == -1 in pg_type must have int32 header with
sizeof () this struct ?

And to better future try dont use words like 'using' to name of variables
because in c++ this words are keywords .... :/

thx
bye
