And I thought I had this solved.

A while back I ran into problems caused by security fix related to the
search path. I wound up adding a line to. for instance, this function:

REATE FUNCTION
work_hours
(
start_date date,
end_date date
)
RETURNS decimal(10,4) stable
language sql as $$

/* workaround for secuirty "feature" */
SET search_path TO ica, "user" , public;

SELECT
sum(case when
extract(isodow from d)
between 1 and 5 then
8.0 else
+0.0 end)
from

generate_series($1,
$2, interval
'24 hours') d;

$$;

And walked away happy, or so I thought. Now I just got this error:

[local] stan(at)stan=# select * from ttl_avail_hours_by_project_and_employee ;
ERROR: SET is not allowed in a non-volatile function
CONTEXT: SQL function "work_hours" during startup

How can I solve this issue?
