[ic] Newb Postgres Session Setup

Hello all,

During my past two weeks of using Interchange, I've been really  
resisting sending a question to the list. However, I think I've run out  
of options.

OS: RH 7.3 (latest updates)
Db: Postgres 7.3
I: 4.9.8-1 (via rpms)

I've followed the instructions via these two posts:


and have adapted it to Postgres vs. MySql. My db structure is as  

- - - [31/July/2003:13:08:49 -0400] - - table user_sessions created:  
create table user_sessions (
 > code varchar(64) NOT NULL PRIMARY KEY,
 > session text,
 > sessionlock varchar(64),
 > last_accessed varchar(32)
 > )

(The varchar(32) for last_accessed vs. timestamp made no difference.)

I *think* the above is ok since I am getting entries in the table for  
the code and sessionlock columns.

psql snip:
store=# select * from user_sessions;
           code          | session |   sessionlock   | last_accessed
  uQDspeRN:XX.XX.XXX.XXX |         | 1059672559:5453 |
  RqeIRN8f:XX.XX.XXX.XXX |         | 1059672562:5456 |
(2 rows)

[ip addrs above have been masked]

So when the session column gets inserted, the DBI.pm file dies with the  
following error:

[31/July/2003:13:09:13 -0400] store /cgi-bin/store/index.html Runtime  
error: DBD::Pg::db do failed: ERROR:  parser: unterminated quoted  
string at or near "'123" at character 36 at  
/usr/lib/interchange/lib/Vend/Table/DBI.pm line 1613.

(Line 1613 is being reported due to a debug statement I inserted at  
line 1612, which is where the error would be thrown on a stock install)

I've looked here as well as other sites regarding the quoted error and  
they all seem to point to some sort of unclosed quote. I've put in some  
debug code in the DBI.pm file to see what was going on and I think it  
might be related to null values being part of the session itself and  
them not being escaped properly. Apparently, Postgres and perl have  
some issues with it - from what I've read on other posts elsewhere.  
But, I'm not at that point in my project where I can dive deep into the  
.pm files and start tinkering.

So I guess I'm looking for a way around this - if it exists. I can move  
sessions back onto the local file store, but ultimately, I want to be  
able to use the db in the future for clustering support. Has anyone  
successfully got this to work with Postgres, or is it a MySql thing  

I'm really having a good time getting Interchange up and going. You  
guys have done a great job :)

Thanks in advance.
