Can someone please help me understand this:
b2bc_dev=# select pg_typeof('a') as a, pg_typeof(array['a']) as arr;
a | arr
---------+--------
unknown | text[]
(1 row)
Why is a text literal on its own 'unknown' whereas in the context of an
array it assumes 'text' ?
This is pg 10.4 in case it matters.
Thanks,
Steve
