This patch fix the Makefiles in contrib/{pginterface, spi,
miscutil, int8, ip_and_mac, sequence, soundex, string, userlock,
array, datetime} to install their modules in one directory(lib/modules/).

Pginterface 2.0 Attached is a copy of the Postgres support routines I wrote to allow me to more cleanly interface to the libpg library, more like a 4gl SQL interface. It has several features that may be useful for others: I have simplified the C code that calls libpq by wrapping all the functionality of libpq in calls to connectdb(), doquery(), fetch(), fetchwithnulls() and disconnectdb(). Each call returns a structure or value, so if you need to do more work with the result, you can. Also, I have a global variable that allows you to disable the error checking I have added to the doquery() routine. I have added a function called fetch(), which allows you to pass pointers as parameters, and on return the variables are filled with the data from the binary cursor you opened. These binary cursors are not useful if you are running the query engine on a system with a different architecture than the database server. If you pass a NULL pointer, the column is skipped, and you can use libpq to handle it as you wish. There is a demo program called pginsert that demonstrates how the library can be used. You can create a library of pginterface.c and halt.c, and just include pginterface.h in your source code. I am willing to maintain this if people find problems or want additional functionality.
