No, I think you could do it with a placeholder if you wanted. The
secret is the (poorly documented) external syntax for a hex bit string:
regression=# select 'xBEEF'::bit varying; varbit
------------------1011111011101111
(1 row)
So it should work to do "SELECT int4($1::bit varying)" and then pass
'xBEEF' as the string value for the parameter.
