Oh, and in 12c, there is cluster agent for MySQL:
http://www.oracle.com/technetwork/database/database-technologies/clusterware/downloads/ogiba-2189738.pdf
Apparently, documentation isn't fully up to date. There is even a
framework for building your own agents:
https://docs.oracle.com/database/121/CWADD/crschp.htm#CWADD91277
And yes, Oracle CRS is free, as long as you don't put something like
ACFS advanced features or Oracle RDBMS on top of it.

I know that there are even open source projects with PostgreSQL and Oracle CRS:

I doubt that anyone would bother with that if that wasn't free.

I can tell if Mladen is correct from his description, this is from the documentation:
The following components of Oracle Grid Infrastructure can be used free of charge and
without any restrictions in standalone server or cluster configurations:
■ Oracle Automatic Storage Management (Oracle ASM)
■ ASM Dynamic Volumes
■ ASM Cluster File System (ACFS) (excludes ACFS snapshots, and other add-on
features)
■ Oracle Clusterware solely in support of ASM/ADVM/ACFS in a cluster
configuration
■ Oracle Restart solely in support of Oracle Databases and Oracle ASM on a
standalone server
In addition, Oracle Clusterware can be used to protect any application (restarting or
failing over the application in the event of a failure), free of charge, if one or more of
the following conditions are met:
■ The server OS is supported by a valid Oracle Unbreakable Linux support contract.
■ The product to be protected is either:
– Any Oracle product (e.g. Oracle Applications, Siebel, Hyperion, Oracle
Database EE, Oracle Database XE)
– Any third-party product that directly or indirectly stores data in an Oracle
database
■ At least one of the servers in the cluster is licensed for Oracle Database (SE or EE)
A cluster is defined to include all the machines that share the same Oracle Cluster
Registry (OCR) and Voting Disk.
