pre-release packages - Mailing list pgsql-pkg-yum

https://yum.postgresql.org/packages/#pg13
v13 PACKAGES ARE FOR BETA TESTING ONLY! USE v12 PACKAGES FOR PRODUCTION.

I think this could elaborate some, and say:
 - the beta packages are built with assertions enabled;
 - the compile options include MEMORY_CONTEXT_CHECKING, which has significant
   negative effect on performance, so packages are not useful for performance
   testing.
