This explains why my suggestion would not work -- I was aware that
specifying a timezone to a TIMESTAMP WITHOUT TIME ZONE resulted in the
time zone being completely ignored -- I assumed that handling of the
value string for a timestampz within the protocol would follow the same
rules.  This also explains why it works correctly when people convert
the timestamp into a string with the desired time zone and insert that
as a literal in place of the ? within the PreparedStatement.

Thanks for the info.

I assume that the behavior of the server when receiving a timestampz
within the protocol couldn't be changed to match the handling of a
literal without breaking significant existing code.

If the target type is actually timestamp (TIMESTAMP WITHOUT TIME ZONE),
the server converts the instant identified by the timestamptz value
using the server's TimeZone setting to get a local date/time, and stores
that.

The string -> timestamp conversion
*completely ignores* the supplied timezone, just using the specified
date/time directly
