Since this version has no scale on the DECIMAL, the second check keeps
it from being larger than 1.0, since it's presumably a percen

Greetings,
I'm attempting to build a version of PG 8.4.1 with the OSSP uuid
libraries on Centos 5.3 (I'm building PG from source). I simply
cannot seem to find the right libraries to install; even very

I'm using PDO in PHP for database access (actually Zend Framework), and

I am porting some code from Perl to Python; in the Perl original I use
either DBI::do or a rickety home-built module to pass multiple SQL

Building from source.
If it's something you built
from source, it more than likely installed into /usr/local/, and
then your problem is that PG isn't searching /

not need to escape the slashes). This g

Here's the first clue:
merlyn=# select '^\/steps\/\?step=10$';

Hi,
Could any one please tell me what is statement ID of table? How to get it
and in which scenarios it can be helpful? Any documentation or example about
statement ID would also really helpful for me.
