I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".
Other major changes:
- pg code now uses only binary format
- pg timestamptz now always UTC (tz = 0), added doc section
- added contracts to most pg "can't-convert" errors
MySQL:
- support multi-packet data rows
- fixed very old length-coding bug (24 vs 32 bit length)
- support large params via long-data packets
- 'any' pseudo-type for parameters
- distinguish 'blob'/'text', 'var-string'/'var-binary'
- read 'text' results as string, not bytes
SQLite3:
- enabled sql types tests
In some cases, statements were disappearing from statement-table
without being finalized; this makes disconnect fail.
(I was only able to produce the problem when the db lib was
instantiated in a sub custodian that is later shutdown....
like the way the rackunit gui runs the test suite.)
