Tom Lane d70a42e642 Represent type-specific length coercion functions as pg_cast entries, ... eliminating the former hard-wired convention about their names. Allow pg_cast entries to represent both type coercion and length coercion in a single step --- this is represented by a function that takes an extra typmod argument, just like a length coercion function. This nicely merges the type and length coercion mechanisms into something at least a little cleaner than we had before. Make use of the single- coercion-step behavior to fix integer-to-bit coercion so that coercing to bit(n) yields the rightmost n bits of the integer instead of the leftmost n bits. This should fix recurrent complaints about the odd behavior of this coercion. Clean up the documentation of the bit string functions, and try to put it where people might actually find it. Also, get rid of the unreliable heuristics in ruleutils.c about whether to display nested coercion steps; instead require parse_coerce.c to label them properly in the first place.		2004-06-16 01:27:00 +00:00
