PostgreSQL 13 is released with some cool features, such as index enhancement, partition enhancements, and many others. Along with these enhancements, there are some security-related enhancements that require some explanation. There are two major ones: one is related to libpq and the other is related to postgres_fdw. As it is known that postgres_fdw is considered to be a “reference implementation” for other foreign data wrappers, all other foreign data wrappers follow their footsteps in development. This is a community-supported foreign-data wrapper. The blog will explain the security changes in postgresq_fdw.
Indexes are one of the core features of all the database management systems (DBMS). Indexes have a very long history in PostgreSQL, which has quite a rich set of index features. PostgreSQL has B-Tree, Hash, GIN, GIST, and BRIN indexes. And because the development around indexes is still going on, PostgreSQL 13 provides some enhancements.
