Thanks for the explanation.
Yeah, here's what's happening. So, yeah, we'll check on having to script it instead.
###
=> select now() ;
now

Is there no way to use \watch to let it run the last script that I just run?
When do I do as below:
select 1 ;
\i x.sql
\watch 20
It runs select 1 instead.
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.
