That ultimately comes from the appendix.

As noted here:

https://www.postgresql.org/docs/current/datatype-datetime.html#DATATYPE-TIMEZONES

There are three ways to specify TimeZone in PostgreSQL. You are using the
third option and thus are dealing with the caveats noted in the third
entry's description and described in detail in the appendix linked to above.

I suggest restricting your use to one of the other two, recommended,
options. If you cannot avoid using the third option you must learn and
abide by its rules.
