I did quite some progress on this PR in the last two days.

Few important first points:

• an endpoint in the dispatcher takes as arg the query in ADQL format, converts it to a postgresql query and runs it, the list of rows (query result) are returned
  • queries in ADQL format are translated in postgresql using the queryparser library
  • a special extension pg_spehere has be installed on the postgresql (strict version requirements apply here) in order to execute certain functions
• the idea is to use a view defined within the gallery DB which is on a MySQL DB
  • thanks to the pgloader the data can be easily transferred from one DB to the other

Why postgresql?

There is an extension, called mysql_sphere, but this is no longer developed and now it's quite outdated. However I gave it a try but I was not able to compile it. I had a brief interaction with the development team of queryparser and they advised against it.

On the contrary, I am testing pg_sphere (running postgresql version 16) and I currently am successful in running ADQL queries using the gallery DB.

I cant really understand this error : https://github.com/oda-hub/dispatcher-app/actions/runs/11054770284/job/30712623502?pr=696

Any ideas? It should not be related to this PR
