Add support for binary I/O of ltree, lquery, and ltxtquery types. Not much to say here --- does what it says on the tin. The "binary" representation in each case is really just the same as the text format, though we prefix a version-number byte in case anyone ever feels motivated to change that. Thus, there's not any expectation of improved speed or reduced space; the point here is just to allow clients to use binary format for all columns of a query result or COPY data. This makes use of the recently added ALTER TYPE support to add binary I/O functions to an existing data type. As in commit a80818605, we can piggy-back on there already being a new-for-v13 version of the ltree extension, so we don't need a new update script file.

Fixed very stupid but important bug: mixing calls of some founctions from contrib/tsearch and contrib/ltree :) Teodor Sigaev 2002-08-11 04:46:24 +08:00			`#define crc32(buf) ltree_crc32_sz((buf),strlen(buf))`
