Issues for linkbench + Postgres

[mdcallag]

From a brave user...

1. Suppose I load 'x' number of nodes. I expect to see 'x' number of rows in nodetable after load phase. With the pervious old version(2011), the number of rows were as expected. But, with the new repository, the number of rows after load phase is '0'. The linktable shows the correct number of rows but not the 'nodetable'. Here's an example

LOAD PHASE COMPLETED.  Loaded 4 nodes (Expected 4). Loaded 961966 links (240491.50 links per node).  Took 811.6 seconds.  Links/second = 1185

Load Phase completed....

Number of rows in linktable: count  
--------
 961966

Number of rows in counttable: count 
-------
     4

Number of rows in nodetable: count 
-------
     0

2. When I use the username 'linkbench' as suggested in the README, it for some reason looks for database with that name. Not sure why. So, it only works when the username is same the database name which is 'linkdb'.

I fixed the docs and then updated pgsql-ddl.sql to use linkdb0 instead of linkdb. There was a recent change to support N db/schemas (linkdb0 to linkdb$(N-1) rather than use linkdb.

But I don't have the Postgres skills to do much more than that and look forward to confirmation from someone who does, or a pull request to fix any other problems.
