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...
             ^
