'Optimize PostgreSQL read-only tables
I have many read-only tables in a Postgres database. All of these tables can be queried using any combination of columns.
What can I do to optimize queries? Is it a good idea to add indexes to all columns to all tables?

If you have filtering by more columns indexes may help but not too much. Also indexes may not help for small tables.
First search for "postgresql tuning" - you will find usefull information.
If database can fit in memory - buy enough RAM. If database can not fit in memory - SSD will help. If this is not enough and database is read only - run 2, 3 or more servers. Or partition database (in the best case to fit in memory of each server).
Even if queries are generated I think they will not be random. Monitor database for slow queries and improve only them.
