That was a miss. I originally tested this on Postgres 14 and of course
it worked. Trying it on Postgres 12 got:

select nullif(1.5, 'inf')::numeric;
ERROR: invalid input syntax for type numeric: "inf"
LINE 1: select nullif(1.5, 'inf')::numeric;

Due to this:

https://www.postgresql.org/docs/current/functions-conditional.html#FUNCTIONS-NULLIF

"The two arguments must be of comparable types. To be specific, they are
compared exactly as if you had written value1 = value2, so there must be
a suitable = operator available."

So:

1.5::numeric = 'inf'::numeric
