postgres can't connect to specific database.

Hi all!

I have a very strange problem. Connect to specific database can't established.
This is the part of my log file:

Nov 11 18:09:00 application postgres[1401]: read_pg_options:
all=0,verbose=1,plan=0,rewritten=0,query=1,syslog=2,locks=0
,hostlookup
Nov 11 18:09:00 application postgres[1401]: debug info:
Nov 11 18:09:00 application postgres[1401]: ^IUser         = postgres
Nov 11 18:09:00 application postgres[1401]: ^IRemoteHost   = localhost
Nov 11 18:09:00 application postgres[1401]: ^IRemotePort   = 0
Nov 11 18:09:00 application postgres[1401]: ^IDatabaseName = isrts
Nov 11 18:09:00 application postgres[1401]: ^IVerbose      = 2
Nov 11 18:09:00 application postgres[1401]: ^INoversion    = f
Nov 11 18:09:00 application postgres[1401]: ^Itimings      = f
Nov 11 18:09:00 application postgres[1401]: ^Idates        = Normal
Nov 11 18:09:00 application postgres[1401]: ^Ibufsize      = 2048
Nov 11 18:09:00 application postgres[1401]: ^Isortmem      = 512
Nov 11 18:09:00 application postgres[1401]: ^Iquery echo   = f
Nov 11 18:09:00 application postgres[1401]: InitPostgres


There are two new files in database directory
-rw-------   1 postgres postgres 18776064 Nov 11 18:09 core
-rw-------   1 postgres postgres        0 Nov 11 18:09 pg_internal.init

How can i decide my problem?
Any help would be greatly appreciated.
