"$user" in a search_path string is replaced by CURRENT_USER not
SESSION_USER. (It actually was SESSION_USER in the initial implementation,
but we changed it shortly later, and evidently forgot to fix the docs to
match.)

If one of the list items is the special name
<literal>$user</literal>, then the schema having the name returned by
- <function>SESSION_USER</function> is substituted, if there is such a schema
+ <function>CURRENT_USER</function> is substituted, if there is such a schema
and the user has <literal>USAGE</literal> permission for it.
(If not, <literal>$user</literal> is ignored.)
