after updating to new version 10.1 Debian, old bash script stopped
working correctly. The thing is, script contains 2 functions which are
called in a loop. But it returns error for some reason.
script is pg_mass_back_error.txt and config for it in attachment
Error:
> Skipping schema template1
> ./pg_mass_back_error.txt: line 50: continue: only meaningful in a
`for', `while' , or `until' loop
