My perl expertise is bit shallow, but I could not find much
regarding bugs related to such behavior, or maybe I did not
look enough.
Playing around with this, "s+", "s{1,}", s{2,}" all of these combinations
where we are searching for more than 1 space result in the hanging command,
but we really only need to look for a single space before the 'version',
so maybe we can just do the below, which works?
- $dump =~ s {(^\s+'version',) '\d+'::integer,$}
+ $dump =~ s {(^\s{1}'version',) '\d+'::integer,$}
