Summary: Cannot create DNS using odbcconf.exe utility in Windows

Initial Comment:
odbcconf.exe /Ld "dsn_llxatnf.txt" /A {CONFIGSYSDSN "PostgreSQL Unicode" "DSN=test1;SERVER=testowy;PORT=5432;DATABASE=testdb;UID=postgres;PWD=postgres;Protocol=6.4;UseServerSidePrepare=1;TextAsLongVarchar=1;ByteaAsLongVarBinary=1;ReadOnly=0;"} /A {CONFIGDSN "PostgreSQL Unicode" "DSN=test2;SERVER=testowy;PORT=5432;DATABASE=testdb;UID=postgres;PWD=postgres;Protocol=6.4;UseServerSidePrepare=1;TextAsLongVarchar=1;ByteaAsLongVarBinary=1;ReadOnly=0;"}

Returns code 0xC0000005.

Message:
I add this new feature to psqlodc. You can try attached patch againist CVS source. If you can't compile psqlODBC please try psqlodbc-8.01.0105 when it's released (I think it could be at the end of week).

Message:
odbconf.exe as input takes pairs keyword-value separated by ";". This string is DIRECTLY distributed to ConfigDSN driver function. ConfigDSN function requires that pairs keyword-value are separated by NULL character (\0). So DSN takes too long value (test1;SERVER=testowy;....) and max DSN name is 32. DSN name is copied over allocated buffer. GlobalFree genearates access violation.

This is not an error. Odbcconf.exe should translate specifed keyword-value pairs as null-separated strings. On the other hand Odbcconf.exe works well with MyODBC driver and many comercial drivers. Maybe PostgreODBC should also accept pairs keyword-value separated by ";"?

Message:
8.01.0104 version still doesn't work with odbcconf.exe. I've trying to create mylog output and there are results:

[1908]globals.extra_systable_prefixes = 'dd_;'
[1908]aszKey='DSN', value='test1;SERVER=testowy;PORT=5432;DATABASE=szakal;UID=postgres;PWD=postgres;Protocol=6.4;UseServerSidePrepare=1;TextAsLongVarchar=1;ByteaAsLongVarBinary=1;ReadOnly=0;Debug=1'
[1908]copyAttributes: DSN='test1;SERVER=testowy;PORT=5432;DATABASE=szakal;UID=postgres;PWD=postgres;Protocol=6.4;UseServerSidePrepare=1;TextAsLongVarchar=1;ByteaAsLongVarBinary=1;ReadOnly=0;Debug=1',server='',dbase='',user='',passwd='xxxxx',port='',sslmode='',onlyread='',protocol='',conn_settings='',disallow_premature=-1)

Not so much as you see.
Return code 0xC0000005 = access violation.
Windows XP SP2.
