pgsql: Change argument of appendBinaryStringInfo from char * to void *

Change argument of appendBinaryStringInfo from char * to void *

There is some code that uses this function to assemble some kind of
packed binary layout, which requires a bunch of casts because of this.
Functions taking binary data plus length should take void * instead,
like memcpy() for example.
