For historical reasons, I have IPv4 addresses stored as bigint and I would
like to convert them to dot-quad (ie. A.B.C.D) in a select. This is how I
would normally do it:
- remotehost is the IP address as a bigint
select
  ((remotehost::bit varying(32) >> 24) & 11111111) || '.' ||
  ((remotehost::bit varying(32) & 11111100) >> 16) || '.' ||
  ((remotehost::bit varying(32) & 11110000) >>  8) || '.' ||
  ((remotehost::bit varying(32) & 11000000)) as ip,
  httpquery
from
 weblogs
;
however this complains:
  ERROR:  Cannot cast type 'bigint' to 'bit varying'
hints?
Thanks,
Adi
