Error!

No GlobalDBH Configured or Could not Connect

Just had this error attempting to install LedgerSMB. In my case this was caused by having postgres-8.3 installed and then installing postgres-8.2 the second installation moved the tcp port to a non-standard port 5433.

Postgres-8.3 is the default version for Ubuntu 8.04, but LedgerSMB at the moment requires postgres-8.2

The solution:
apt-get remove --purge postgres-8.3
edit /etc/postgres/8.2/main/postgresql.conf and set the option "port = 5432"
Restart postgres *note don't do a restart do a start and stop
/etc/init.d/postgres-8.2 stop
/etc/init.d/postgres-8.2 start

Of course you could simply edit ledgersmb.conf and change the [globaldb] section DBport value to be the port which Postgres 8.2 is running on.
