Correct, sort of. GridSQL is not part of the core server, it is a
separate Java-based distributed database which front-ends a cluster of
Postgres servers.
Originally, GridSQL was written to be database independent. However,
over the last year, it has been specialized for Postgres. Some of
these specializations include support of the Postgres wire-level
protocol, an understanding of Postgres SQL syntax, etc. Coming
versions of GridSQL will support more native Postgres features and may
benefit from some of our internal changes to the database core.
Regardless, it is open source and should always run against standard PostgreSQL.
