I wonder if "hanging" actually means that it interpreted the sleep time
as a very large integer, so it's just sleeping for a long time.
About the server locale, note that the ->new() call explicitly requests
the C locale -- it's only psql that is using the Czech locale.
Supposedly, the Perl code should also be using the Czech locale, so the
sprintf('%g') should be consistent with what psql \watch expects.
However, you cannot ask the server to be consistent with that -- say, if
you hypothetically tried to use "to_char(9D99)" and \gset that to use as
\watch argument, it wouldn't work, because that'd use the server's C
locale, not Czech. (I know because I tried.)
