Why does PEAR DB give "DB Error: extension not found [DB Error: extension not found].."
I'm moving a small set of PHP/Postgres applications from Ubuntu 9.x to 10.10. When I try to run the application, I get this error:
DB Error: extension not found [DB Error: extension not found] ** pgsql://jean@/appx
The code is:
require_once('DB.php');
$db=DB::connect("pgsql://j
if (PEAR::isError($db)) {
die($db->getMessage()." ".$db->getUserInfo()." ");
}
if (DB::isError($db)){
die($db->getMessage());
}
When I installed DB, I noticed that it's been supersceded by MDB2, what do I have to change to make it work with MDB2, or what do I need to do make the DB code work?
Thanks.

When I used 'php5-psql' as the package name, it said there was no such package. On a hunch, I tried 'php5-pgsql' instead, and it did download & install it, but I still get the error.
Sorry, it's more likely you're missing the Pear extension. My guess is that when you upgraded, the php extension directory probably changed. If this is the case, you'll need to reinstall the DB package. However, what I would do is try the MBD2 package first. If that fails, just re-install DB.
$ pear install MDB2
Make sure there are no errors, and take note of whether Pear has enabled the extension for you or not. You can post the last couple of lines from the output here.

Both those packages appear to be installed:
root@Ubuntu:/home/jean# pear install MDB2
pear/MDB2 is already installed and is the same as the released version 2.4.1
install failed
root@Ubuntu:/home/jean# pear install DB
pear/DB is already installed and is the same as the released version 1.7.13
install failed
If DB was missing, wouldn't I get an error on the require_once('DB.php') statement?
Also, just to clarify, I'm not upgrading a machine, I have a brand new machine and I copied the php pages from the old server to the new server.

Now I get:
MDB2 Error: connect failed _doConnect: [Error message: unable to establish a connection] ** pgsql(pgsql)://jean:xxx@/a
Not sure what the problem is here. This user can run psql, access the 'appx' database, view tables, etc, etc. Maybe there's a problem in the postgres setup that prevents connections from apache?

Would you be able to temporarily switch back to DB? It seems to me that DB does error reporting more constructively than MDB2, by default anyway.
Perhaps there's a setting to make MDB2 spit out more details, but I'm not sure where to look for that. But if we can get it working with DB, we should then be able to get it working with MDB2 also.
I'm assuming you have PostgreSQL installed?
$ sudo aptitude install postgresql

Hooray! Just switching back to DB solved the problem, everything works as it should!
I guess the problem all along was I needed to install the php5-mysql package.
Thanks for the help!

The problem was the missing php5-mysql part of PEAR. After installing that, it was not necessary to change anything.
Good stuff! Glad I could help.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

See if the following works for you:
$ sudo aptitude install php5-psql
(Inside a terminal window, of course)
