postgresql-15-hll
HyperLogLog extension for PostgreSQL
This PostgreSQL module introduces a new data type `hll` which is a HyperLogLog
data structure. HyperLogLog is a fixed-size, set-like structure used for
distinct value counting with tunable precision. For example, in 1280 bytes
`hll` can estimate the count of tens of billions of distinct values with only
a few percent error.
postgresql-15-debversion
Debian version number type for PostgreSQL
Debian version numbers, used to version Debian binary and source
