Likewise, the current session's temporary-table schema,
<literal>pg_temp_<replaceable>nnn</></>, is always searched if it
exists. It can be explicitly listed in the path by using the
- alias <literal>pg_temp</>. If it is not listed in the path then
+ alias <literal>pg_temp</><indexterm><primary>pg_temp</></>. If it is not listed in the path then
it is searched first (even before <literal>pg_catalog</>). However,
the temporary schema is only searched for relation (table, view,
sequence, etc) and data type names. It is never searched for
temporary-table schema, which is searched first by default, and
is normally writable by anyone. A secure arrangement can be had
by forcing the temporary schema to be searched last. To do this,
- write <literal>pg_temp</> as the last entry in <varname>search_path</>.
+ write <literal>pg_temp</><indexterm><primary>pg_temp</><secondary>securing functions</></> as the last entry in <varname>search_path</>.
This function illustrates safe usage:
