Watch is documented to act on either a non-empty query buffer or the last
sent command.  I would expect that whatever the final SQL command present
in x.sql is would be the command that gets watched.  If indeed the
preceding select 1 command is watched there would seem to be an
undocumented interaction going on.

In any case, no, you cannot watch a meta-command.  You’d have to resort to
shell scripting the repeated execution of the psql program itself.
