Thread: bitfromint4() in v7.2.3 to bit() in v8.1?
Hi,
In version 7.2.3 this works fine:
select substring(bitfromint4(cast (-2^31 + 22 as int4)), 1, 32);
and now I'm porting the legacy code, that this line is part of, to version 8.1 but am having no luck updating it - have tried something like:
select substring(bit(cast (-2^31 + 22 as int4)), 1, 32);
and
select substring("bit"(cast (-2^31 + 22 as int4)), 1, 32);
and
select substring(1::"bit"(cast (-2^31 + 22 as int4)), 1, 32);
with no luck.
How can this be solved?

Use a cast, eg
regression=# select cast (-2^31 + 22 as int4)::bit(32); bit
