Hello,
I'm currently running version 07_03_0200 of the Insight Distribution
Systems PostgreSQL Driver for windows. when I retrieve col1 string
from the database using: "SELECT * FROM MyTable WHERE col1='hello\n'"
the value returned for col1 through the driver is "hello\r\n", and I
want it to be as it is stored in the database ('hello\n" with no \r).
Is this a configuration issue? If so, where can I change the
configuration to ensure that this conversion won't happen?
Thanx in advance for your help, amir
PS: This is a mailing list thread I ran across that had the same
problem. does anybody know if the bug has been fixed? I tried
contacting Byron, but his email is no longer valid:

Actually, its LF to CR/LF when going from the database to odbc. When going the
other way (odbc->database), it converts CR/LF to LF. The reason is for
Microsoft from what I remember. It might have even been in the odbc spec (I
can't quite remember). It probably shouldn't do it if its being run on Unix
though?

Good Job, you found a bug alright! It should be strlen(ptr). When I tested
it, I didn't have newlines so it worked ok.
I'll put it in for the next release.
