Summary: Long parameters are not parsed from initialization string and unitialized options

Initial Comment:

SQLConfigDataSource( NULL,ODBC_CONFIG_DSN,
"PostgreSQL Unicode",
"DSN=Example\0SERVER=localhost\0DATABASE=template1\0Username=postgres\0UseServerSidePrepare=1\0TextAsLongVarchar=1\0ByteaAsLongVarBinary=1\0\0")

This creates new DSN but options such as ByteaAsLongVarBinary and TextAsLongVarchar are set to -1 instead of 1. Thats because ParseAttributes function in SETUP.C file accepts only keys smaller then 15 characters:

#define MAXKEYLEN (15+1) /* Max keyword length */
char aszKey[MAXKEYLEN];

There are some options much longer than 15 chars an they are not parsed.

In general uninitialized options shouldn't be saved in registry (ODBC.INI) but CC_conninfo_init initializes some options to -1 and they are never updated to proper default values:

// connection.c
CC_conninfo_init(ConnInfo *conninfo)
{
memset(conninfo, 0, sizeof(ConnInfo));
conninfo->disallow_premature = -1; //!!
conninfo->allow_keyset = -1; // !!
conninfo->lf_conversion = -1; // !!
conninfo->true_is_minus1 = -1; // !!
conninfo->int8_as = -101;
conninfo->bytea_as_longvarbinary = -1; //!!
conninfo->use_server_side_prepare = -1; //!!
memcpy(&(conninfo->drivers), &globals, sizeof(globals));
}
