PostgreSQL 14.2-1
Dear readers,
it used to be possible to say (inside plpgsql):
if _value is of (text, char, varchar, name) then
val_type := ''string'';
elsif _value is of (smallint, integer, bigint, numeric, boolean) then
val_type := ''numeric'';
elsif _value is of (bytea) then
val_type := ''data'';
elsif _value is of (text[]) then
val_type := ''str_array'';
else
raise exception ''cfg.set_option(text, any, text, text, text): invalid type of value'';
end if;
where _value is some typed value.
As of now (not sure when that started) PG 14 is giving me
gnumed_v23=> select 'a'::text is of (text, integer);
ERROR: syntax error at or near "of"
(same thing inside plpgsql)
where the log says
2022-04-23 19:58:33 GMT ERROR: 42601: syntax error at or near "of" at character 21
2022-04-23 19:58:33 GMT LOCATION: scanner_yyerror, scan.l:1176
2022-04-23 19:58:33 GMT STATEMENT: select 'a'::text is of (text, integer);
I can't find anything in the changelog saying that "is of"
was removed. For what it's worth, nothing in the docs ever
said it existed either (though it did, as per real life).
Now, pg_typeof is an alternative but that only goes so far:
it requires laboriously constructing an array on the right
hand side for the above use case, along the lines of:
select pg_typeof('a'::text) = any(ARRAY[pg_typeof(''::text), pg_typeof(''::name)]);
Is there anything obvious I am missing for easily
resurrecting the above "is of" use ?
Thanks,
Karsten
