is there a some special reason to divide diff to separate parts?

I can't to compile code

execAmi.c: In function ‘ExecReScan’:
execAmi.c:186: error: ‘exprCtxt’ undeclared (first use in this function)
execAmi.c:186: error: (Each undeclared identifier is reported only once
execAmi.c:186: error: for each function it appears in.)
make[3]: *** [execAmi.o] Error 1
make[3]: Leaving directory `/home/pavel/src/pgsq

because Tom commited significant changes in executor

When I looked to documentation I miss a some tutorial for foreign
tables. There are only reference. I miss some paragraph where is
cleanly and simple specified what is possible now and whot isn't
possible. Enhancing of dblink isn't documented

Why you don't use PQescapeLiteral for escaping. Isn't
escape_param_str redundant and unsecure?

In function  pgIterate(ForeignScanState *scanstate) you are iterare
via pg result. I am thinking so using a cursor and fetching multiple
rows should be preferable.
