PGconn

Can anyone tell me what are the 3rd and 4th argument of PGconn#connect
method
in ruby ? .

pgoptions and pgtty? I’ll give them one thing, they’re really useful
names.

pgoptions: backend options (String)
pgtty: tty to print backend debug message (ignored in newer versions of
PostgreSQL) (String)

Cheers,
Dan

Google’s really helpful :wink:

I had a look on this URL . I think that pgoptions is psql command line
options . Because when the error comes to this methods it says hint as
follows ,

Error: ./TransactionProcessor.rb:15:in connect': FATAL: invalid command-line arguments for server process (PGError) HINT: Try "postgres --help" for more information. from ./TransactionProcessor.rb:15:in initialize’
from ./TransactionProcessor.rb:30:in `new’
from ./TransactionProcessor.rb:30

coding : PGconn.connect(
POSTGRES_SERVER,POSTGRES_PORT,“-x”,“”,POSTGRES_DATABASE,POSTGRES_USERNAME,POSTGRES_PASSWORD
)
here ,
-x means Turn on the expanded table formatting mode. This is
equivalent to the \x command .

Can you tell me what is pgoptions ?

Well I’ve just had a horrible flash back of getting the PG driver!

My PGconn code looks as such

pghost = ‘localhost’
pgport = 5432
pgtbl = ‘tweek’
dbname = ‘postgres’

db = PGconn.connect(pghost, pgport,’’,’’,pgtbl,dbname,’’)

Have you tried the \x as the third option?
Failing that, sign up to the postgres mailing list. They may be able to
point you in the right direction.
