Waiting for PostgreSQL 18 – Support RN (roman-numeral format) in to_number().

Read Original

The article details a new feature in PostgreSQL 18: support for the RN (Roman numeral) format in the to_number() function. This allows converting Roman numeral strings (like 'MCMLXXXIV') back to integer values (1984), complementing the long-existing to_char() function for Roman numeral output. It highlights the community contribution process behind the patch.
