I see no problem without Unicode support. I'm not sure with unicode version.

RETCODE SQL_API PGAPI_GetInfo(
HDBC hdbc,
UWORD fInfoType, // 18
PTR rgbInfoValue, // output buffer
SWORD cbInfoValueMax, // size of output buffer
SWORD FAR * pcbInfoValue) // returned length
{
char *p = NULL,
tmp[MAX_INFO_STRING];
int len = 0;

....

switch (fInfoType)
case SQL_DBMS_VER:
snprintf(tmp, sizeof(tmp) - 1, "%s %s", POSTGRESDRIVERVERSION, conn->pg_version);
tmp[sizeof(tmp) - 1] = '\0';
p = tmp;
break;

....

result = SQL_SUCCESS;

if (p) {
len = strlen(p);
#ifdef UNICODE_SUPPORT
if (conn->unicode)
len = len * WCLEN;
#endif
if (rgbInfoValue) {
#ifdef UNICODE_SUPPORT
if (conn->unicode)
len = utf8_to_ucs2(p, len, (SQLWCHAR *) rgbInfoValue, cbInfoValueMax / 2);
else
#endif
strncpy_null((char *) rgbInfoValue, p, (size_t) cbInfoValueMax);

if (len >= cbInfoValueMax) {
result = SQL_SUCCESS_WITH_INFO;
CC_set_error(conn, CONN_TRUNCATED, "The buffer was too small for the InfoValue.");
}
}
}

....

if (pcbInfoValue)
*pcbInfoValue = len;

mylog("%s: p='%s', len=%d, value=%d, cbMax=%d\n", func, p ? p : "<NULL>", len, value, cbInfoValueMax);

return result;
}

I have no time for this issue until next week. The code is located
in info.c.

Luf

I test unicode driver 08.01.0106 on CentOS 4.2 x86_64 without such problem.
I have no Fedora 4 x86_64 to test it.

Perl code to test (it needs DBD::ODBC):

use DBI;

my $dbh = DBI->connect('dbi:ODBC:<DSN>','username','password') ;
print $dbh->func(18, GetInfo);
$dbh->disconnect;

Could someone test it with Fedora 4 on x86_64?

Thanks,

Luf

Argh, false alarm: the reporter was *not* using psqlodbc, he was using
the ancient and unmaintained version embedded in the unixODBC package.
That predates the bug fix applied here:
http://cvs.pgfoundry.org/cgi-bin/cvs...1=1.89&r2=1.90

Sorry for the noise.
