Hello.
Your toll Schema Diff tool has saved me a lot of time and nerves, but I
encountered one unpleasant problem when creating scripts for functions. The
synchronization strategy involves creating source functions and deleting
target functions. In most cases this works. But if a function changes its
output type or output parameters, it is not considered an overload in
PostgreSQL, and it is impossible to create such a function before deleting
it in the target, which leads to script execution errors.
