supported_dbs.json. is the file that lists the supported databases. Even if the database is listed, it is required to also install the related driver.

Indexima provides this updated file every release.

You can manually modify the new JSON line like this :

"name": "postgresql", // Name of the database
"only_physical_table": true, // False if it supports external table
"driver": "org.postgresql.Driver" // JDBC Driver class to use
