Makes no difference whether month or months:
moodle-01-01-2009=# select time, to_timestamp(time) AS ts, extract('month','to_timestamp(time)') from mdl_log LIMIT 10;
ERROR: syntax error at or near ","
LINE 1: ...ct time, to_timestamp(time) AS ts, extract('month','to_times...
^
moodle-01-01-2009=# select time, to_timestamp(time) AS ts, extract('months','to_timestamp(time)') from mdl_log LIMIT 10;
ERROR: syntax error at or near ","
LINE 1: ...t time, to_timestamp(time) AS ts, extract('months','to_times...
^
