Colin Dellow 824a416f51 better debug logs for xBestIndex 2018-03-08 13:21:33 -05:00
Colin Dellow 0d4806ca6f Rejig parquet generation 
- "fixed_size_binary" -> "binary_10"
- make null parquet use rowgroups of sie 10: first rowgroup
  has no nulls, 2nd has all null, 3rd-10th have alternating
  nulls

This is prep for making a Postgres layer to use as an oracle
for generating test cases so that we have good coverage before
implementing advanced `xBestIndex` and `xFilter` modes.

Colin Dellow 552da5a647 Initial checkin of CSV table 
parquet.cc is a fork of the sample CSV virtual table at
https://www.sqlite.org/src/artifact?ci=trunk&filename=ext/misc/csv.c

So far the only changes are those needed to make it compile cleanly in
C++11 mode.
