Hi, list! I wish I have a tool which would compare two database
sachemas, where each schema is represented as a list of 'CREATE smth'
instructions. The result of such a comparison would be a list of
'ALTER smth' instructions. This instruction set would change the
database from first state to second, if the transition is possible
without data losses. The 'hard' mode - to prepare the transition for
any inputs, with minimal data losses.
The database of interest is PostgreSQL. Does such a tool exist? If
not, which package do I better use to build the AST of initial
The example schema is in attach.
Thanks in advance,
