June 7, 2004 - 1.1:
Syslog parser now handles durations.
Added text versions of duration reports.
Removed some spurious entries from the reports (i.e., BEGIN;ROLLBACK).

May 17, 2004 - 1.0:
Now numbers are normalized - i.e.; "select bar where foo=222" normalizes to the same query as "select bar where foo=123312321".  This means more accurate information on what queries are occurring most frequently, taking the most time, and all that.
Fixed bug - OverallStatsReport no longer displays "longest ran in 0.0 seconds" if the log does not include duration information
Fixed bug - OverallStatsReport now displays the correct number of unique queries.  v0.9 listed the same number for both total and unique queries.
Fixed various bugs in syslog parsing - now it should work better with both PG 7.3 and PG 7.4.  It's still a better idea to use the Postgres log, but if you must use syslog for some reason, it's better now.

May 11, 2004 - 0.9:
Added ability to handle Postgres logs where log_pid/log_timestamp/log_connection has been enabled
Modified to support both "query:" and "statement:" as log entry preambles - i.e., works with PG 7.4 logs now.
The SQL colorizing works a bit better.
Updated documentation to include better postgresql.conf configuration details.

May 7, 2004 - 0.8:
Added UPDATE queries to the "Queries by type" report
Added support for parsing query duration data from the Postgres log
Added a "Queries that took up the most time" report
Added a "Slowest queries" report
Added a table of contents to the HTML report

April 28, 2004 - 0.7:
Added support for using Postgres log file.  syslog is still supported, of course.
Fixed bug which resulted in errors if the number of valid queries in a log was less than -top.  Thanks to Tom De Bruyne for reporting this bug.
The SQL colorizing works a bit better now.
Various tweaks to HTML reports.

April 23, 2004 - 0.6:
Added a 'rank' column to the 'MostFrequentQueries' report.
Colorized the SQL keywords in the HTML report.

April 7, 2004 - 0.5:
Added HTML reports.

April 6, 2004 - 0.4:
Fixed a bug which prevented single digit date logs from being parsed.

March 17, 2004 - v0.3:
Fixed an off-by-one bug in the number of reports returned.
More optimizations, should again be about 10% faster.
Added a "query frequency by type" report.

March 9, 2004 - v0.2:
Fixed a connection id bug.
Various optimizations, should be about 10% faster.
Improved packaging.

March 5, 2004 - v0.1:
Can display queries by frequency.
Performs query normalization.
