    LZ4 and ZSTD pg_dump compression in PostgreSQL 16

    LZ4 and ZSTD pg_dump compression I wrote a “pg_dump compression specifications in PostgreSQL 16” post a while ago. Frankly speaking, I thought new compression methods would not be implemented in PostgreSQL until 2-3 years from now. Probably demand is so high that LZ4 and ZSTD made their way into PostgreSQL 16! The LZ4 patch author […]

    New old “debug_parallel_query” setting in PostgreSQL 16

    Naming variables Why will force_parallel_mode – the runtime option be renamed to debug_parallel_query in PostgreSQL 16? Proper variable and function naming play a vital role in making code understandable, maintainable, and easily shareable. When we give our variables descriptive names that reflect their purpose, it becomes much simpler for others to understand our code, follow […]

    usql: universal psql?

    usql? But why? usql is a universal command-line interface for many database. But why are we still using CLI (command line utilities) in the 21st century? And what is wrong with psql?

    hex, oct, bin integers in PostgreSQL 16

    SQL and integer notations NEW in PostgreSQL 16 – support for non-decimal notation of integer constants! PostgreSQL already has powerful support for string constants, with E’\t’, E’\011′, E’\u0009′ and U&’\0009′ all meaning the same thing (a “horizontal tab” character). However, PostgreSQL’s support for numerical constants has – up until now – been rather limited; it […]
