I don't see that warning with my compiler so I have no way of testing
this, but I do see this line pretty high in the function:

tableinfo.relkind = *(PQgetvalue(res, 0, 1));

Do you have any idea how relkind could be accessed before this
assignment? The line number is it complaining about is the definition
of relkind in the structure, not any reference to the variable.

The only crazy idea I have is that the variable name appears in a string
above the assignment:

"SELECT relhasindex, relkind, relchecks, reltriggers, relhasrules, "

And relkind is the only column that matches a structure member.
