update of 19 Nov 2003


Please enter a FULL description of your problem:
------------------------------------------------
1) table contains a valid inet field
2) query works fine in pgsql 7.2 & 7.3
3) query no longer works in pgsql 7.4

select * from <table> where <field> ilike '%<inetvalue>%' ;

fails with:
ERROR:  Unable to identify an operator '~~*' for types 'inet' and
'"unknown"'
        You will have to retype this query using an explicit cast


Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------

select * from ipaddrs2 where ip2_address ilike '%10.123.252.4%' order by
ip2_address asc;

CASTing the operator provides no resolution, as it causes syntax errors,
ie:
select * from ipaddrs2 where ip2_address ilike '%10.123.252.4%'::inet
order by ip2_address asc;
returns:
ERROR:  invalid INET value '%10.123.252.4%'
AND:
select * from ipaddrs2 where ip2_address ilike CAST('%10.123.252.4% as
inet) order by ip2_address asc;
returns:
ERROR:  invalid INET value '%10.123.252.4%'

If you know how this problem might be fixed, list the solution below:
