Inconsistencies in the behavior of CHR() function in PG. - Mailing list pgsql-hackers
Hi All,
While trying to explore on CHR() function in PG,
I found that few of the ASCII values are returning hex number values(like '\x08', '\x0B')
and few are executing within SQL (i.e. chr(9) => Horizontal tab, chr(10) => Line feed) as below example.
postgres=# select 1|| chr(8)|| 2 || chr(9)||3 || chr(10)||4 || chr(11)||5 || chr(12)||6 || chr(13)||7 as col1;
col1
----------------
1\x082 3 +
4\x0B5\x0C6\r7
(1 row)
My question here is, why these inconsistencies in the behavior of CHR() function?
