Trusted Language Extensions for PostgreSQL (pg_tle) now supports new crates for PL/Rust such as croaring-rs and num-bigint, enabling you to build more of your extensions on RDS for PostgreSQL. PL/Rust, a PostgreSQL trusted procedural language, lets users build high performance, memory safe user defined functions with the resource efficiency of compiled languages like C.
Rust crates extend functionality in PL/Rust to help support more use cases such as for analytics, search, and security applications. croaring-rs adds support for roaring bitmap, a data type that provides better compression and lower memory utilization compared to conventional bitmaps. Roaring bitmaps are used for applications that require high performance lookups with a high compression ratio, such as analytics and big data. The num-bigint crate adds precision handling for arbitrarily large sized integers, which is used for security and scientific applications.
pg_tle is an open source development kit to help you build extensions written in a trusted language, such as PL/Rust, that run safely on PostgreSQL. Support for num-bigint and croaring-rs crates is available on database instances in Amazon RDS running PostgreSQL 16.1-R2 and higher, 15.5-R2 and higher, 14.10-R2 and higher, and 13.13-R2 and higher. To learn more about using pg_tle, see our Amazon RDS User Guide.
Amazon RDS for PostgreSQL helps make it easy to set up, operate, and scale PostgreSQL deployments in the cloud. Amazon RDS for PostgreSQL is available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD See Amazon RDS for PostgreSQL Pricing for pricing details and regional availability.
