Agreed. I have gotten confused on how to set $user in the past. I have
developed the following patch that sets the default with the double
quotes around it, and it works fine. The patch also contains updated
documentation.
I just never realized that dollar signs have to be double-quoted, but I
it makes sense now that I see it:
test=> select lanname as $user from pg_language;
ERROR: syntax error at or near "$" at character 19
LINE 1: select lanname as $user from pg_language;
^
test=> select lanname as "$user" from pg_language;
$user
----------
internal
c
sql
(3 rows)
Are the quotes an improvement?
search_path
----------------
"$user",public
(1 row)
test=> set search_path = "$user",public;
SET
