On several occasions I have wanted to input integers in hexadecimal rather than in decimal in PostgreSQL. I notice that there is a to_hex function, but there is not (AFAIK) a way to provide an integer in hexadecimal.
I have written a pure-sql implementation of some functions to input integers in hexadecimal (http://postgresql.jdrake.com/hex-int-in.sql.html), but it is less than efficient ;) Is there some reason why hex input is not currently supported? What would be the preferred way to implement it? 1. A function (or one for each int[248]), essentially from_hex(text) 2. Support in the input functions for int[248] for integers that start with '0[Xx]' as with strtol with base set to 0. 3. Support in the grammar for integral constants 0[Xx][0-9A-Fa-f]+ Thoughts? Is this a legitimate TODO? -- Mr. Cole's Axiom: The sum of the intelligence on the planet is a constant; the population is growing. ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
