Support for multiple queries per SQL file

[radim]

Hi @dimitri

I have added support for multiple querier per SQL files as supported by other tools. It does support both the original single query per .sql file and multiple queries (each tagged individually).

1. single queries support (if not tagged) uses name default
2. otherwise named tag is used

The most significant change introduced by this PR is naming of the plan files (and other relevant files). New naming changes from query_file.ext to query_file-query_name.ext.

What are your thoughts on this? I understand you might have some particular idea in mind when going with the only single query per file approach. Would be interested to find out more.

If you are happy to go ahead - I would still have to update Example section of README.md.

Cheers!

Hi @radim ! Thanks for your contribution! do you want to enrol as a collaborator on this project and then have the chance to merge your PR yourself, and maybe maintain the project to some extend?

@dimitri sorry for late response. That would be awesome! In my spare time I'm working on stack to support easier development cycle for Go based projects and regresql is big part of it

@radim and @dimitri is there a reason why this PR was never merged?

I'm looking into starting using regresql and it would be important to have support for multiple queries per SQL file.

I have some Golang experience and could help with code, tests, and documentation.

Thank you!
