Have you tried:
NULLIF(cept.value, 'inf')::numeric
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
The cheat would be:
select version();
version

PostgreSQL 12.10 on x86_64-pc-linux-gnu, compiled by gcc (SUSE Linux)
7.5.0, 64-bit
select nullif('inf'::float, 'inf')::numeric;
nullif
--------
NULL
select nullif(1.5::float, 'inf')::numeric;
nullif
--------
1.5
