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 f8599f8d3e Rename some references to CSVs
...some nonsensical things, like "first row of Parquet",
but we'll tidy them up later.

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.
