Pigsty v2.7: Extension Overwhelming

I wrote a popular article last month - Postgres is eating the database world, explaining why extensions matter to the PostgreSQL ecosystem.

Based on this idea, we’ve packaged 20 brand-new extensions in v2.7. With these extensions added, Pigsty offers 157 non-contrib extensions for EL Distros and 116 for Debian/Ubuntu Distros. Combined with 73 built-in Contrib extensions, Pigsty now has a total of 255 unique extensions available, which takes PostgreSQL’s versatility to a whole new level!
