TIME<space>ZONE is a special case as detailed at the top of:
https://www.postgresql.org/docs/9.6/static/sql-set.html

Specifically, for "time zone" there is no "to" between "time zone" and the
zone name but "local" is a special-case allowed option which is not one of
the options for configuration parameters (local would not make sense for
most configuration parameters while default usually does).

But "timezone" (no space) is a configuration parameter and *does* require
the "to".

Won't work:

steve=# alter database steve set timezone local;
ERROR: syntax error at or near "local"
LINE 1: alter database steve set timezone local;
^
steve=# alter database steve set time zone to local;
ERROR: syntax error at or near "to"
LINE 1: alter database steve set time zone to local;

steve=# alter database steve set timezone 'US/Eastern';
ERROR: syntax error at or near "'US/Eastern'"
LINE 1: alter database steve set timezone 'US/Eastern';

steve=# alter database steve set timezone to 'local';
ERROR: invalid value for parameter "TimeZone": "local"

Will work:

steve=# alter database steve set time zone 'US/Eastern';
ALTER DATABASE

steve=# alter database steve set time zone local;
ALTER DATABASE

steve=# alter database steve set time zone default;
ALTER DATABASE

steve=# alter database steve set timezone to 'US/Eastern';
ALTER DATABASE

steve=# alter database steve set timezone to default;
ALTER DATABASE

I know - I was just showing both the privileged and unprivileged attempts.
