All I can say is, way cool. Pity you couldn't get the necessary support
but if you can put it up in a way so it can be easily packaged by
distributors that'd be cool. I can think of some projects that could
really benefit from a feature like this.
Have a nice day,
We are working on a version to put on pgfoundry. This version will add
stub functions to libpq and have the meat of the pqtypes in separate
shared library: loadable via
PQtypesLoad(){
dlopen("libpqtypes.so");
dlsym("pqt_paramExec");
dlsym("pqt_paramCreate");
// etc...
}
Maybe we'll get enough support in the future to get our stubs into core.
Until then, you'll have to patch libpq. We plan to provide binary
patches for the major platforms. You won't have to patch the guts of
pqtypes though because that is dynamically loaded behind PQtypesLoad ...
you just need libpqtypes.[so|dll] in your libpath.
