Good day.
System Configuration
---------------------
Architecture: Intel Pentium
Operating System: 4.2-STABLE FreeBSD
PostgreSQL version: PostgreSQL-7.0.2
Compiler used: gcc 2.95.2
Description of problem
----------------------
It's some differences in results, then I inserted char(1) type. I introduce one
example:
create table ku(n_pp int4, col char(1));
insert into ku values(1, '\000');
insert into ku values(2, '\040');
insert into ku values(3, ichar(0));
insert into ku values(4, ichar(32));
select n_pp, ascii(col) from ku ;
n_pp | ascii
------+-------
1 | 32
2 | 32
3 | 0
4 | 32
(4 rows)
Look at the strings where "n_pp" equal 1 and 2. "Col" column always equals to 32
(decimal), but I inserted as '\000' and '\040'. (It is first way).
In second way, If I use ichar() function, then "col" column has another
values. This result is correct (I think).
Is it right ?
Locales for "postgres" user adjust properly (if it's necessary).
ps. I use some function from list, which generated by "\df" command from psql
console. But I didn't found them in pgsql documentation. Is it possible that
this function will be removed in future version of postgresql ?
pps. Can I take description of this function ?
sorry for my bad english ;)
Regards..
