[RCD] Release Candidate for version 1.3 available for download

[Ralph Plawetzki]

Dear RC devs,

thanks for the beta.
I noticed some changes to database patches [1]. My RDBMS is PostgreSQL. 
Usually on an RC update if there are new files in the SQL/postgres/ 
directory I apply them to the RDBMS.

With the beta, these files were changed:
SQL/postgres/2016081200.sql
SQL/postgres/2016100900.sql
SQL/postgres/2016112200.sql
SQL/postgres.initial.sql

How to reflect these changes in my DB? Or does this not matter for me 
unless I use a GaleraCluster?

Thanks.

Kind regards,
Ralph
