to be sure the documentation of that storage would be needed. But my educated guess is:
select get_byte(decode(substring('52e1fcb6',1,2),'hex'),0)||'.'||
get_byte(decode(substring('52e1fcb6',3,2),'hex'),0)||'.'||
get_byte(decode(substring('52e1fcb6',5,2),'hex'),0)||'.'||
get_byte(decode(substring('52e1fcb6',7,2),'hex'),0)
of course translated to:
select get_byte(decode(substring("columname",1,2),'hex'),0)||'.'||
get_byte(decode(substring("columname",3,2),'hex'),0)||'.'||
get_byte(decode(substring("columname",5,2),'hex'),0)||'.'||
get_byte(decode(substring("columname",7,2),'hex'),0) from yourtable
where "columname" is the name of the column with the IPs.
Best wishes,

Dear Friends,
My PhpBB forum with 4000 users was hacked in Switzerland.
Enquirers (not my own idea) proposed that I look for certain IPs in my
PostgreSQL 8.2 database. The problem is that PhpBB stored IPs as
strings, which seem to be more or less encoded.
In PhpBB, IPs are stored as Hexa:
"54dc0636"
"52e1fcb6"
How to cast these values to readable content?
Any idea ? This is an important issue for me.
Thank you for any help.
Kind regards,
Jean-Michel
