X.509 certificate parsing library for PostgreSQL using zstandard compression
This is a fork from original libx509pq using zstardard with a custom dictionary to achieve about 50% compression per certificate resulting in about 20-30% less storage usage.
The custom dictionary is stored in the zdict.bin for usage outside this library.
If your filesystem provides good compression, like ZFS does, the usage of this library doesn't not help much achieving just marginal results in expense of adding more complexity.
