[pgrouting-users] RFC3 Positional and named parameters on pgRouting functions

[Daniel Kastl]

Hi Dave,

Thanks a lot for the feedback!

The proposal, we're talking about, will apply for the next major release of
pgRouting. And major releases often imply some "breaking changes", because
sometimes wrong decisions have been made, and major releases try to fix
them.

There will be definitely documentation, that explains breaking changes and
what to care about when upgrading. Eventually there are ways to provide
even more user-friendly upgrade tools. Suggestions are always welcome!

However, the RFC3 proposal actually tries to make function syntax more
reliable. By using named parameters the order or number of function
parameters may change but your application will still work.

Best regards,
Daniel
