So, to put that to rights, here's a pgAdmin update. For the last few days I've been working on cosmetic and usability issues in the user interface, and consequently, 1.6.0 (when released) will sport a fancy new docking user interface on the main windows, allowing you to arrange elements as you like, detach panes, move toolbars around and display or hide individual elements. There are also popup docking hints to make it easy to re-dock elements exactly where you want them...
Other recent improvements include a host of tweaks to the Query Tool including regexp search and replace, error word highlighting and brace matching, as well as enhancements elsewhere such as the ability to display and set boolean columns to NULL in the Data Editor, an XML/XHTML reporting engine with a host of schema and data reporting options and initial support for the PostgreSQL 8.2-dev.
Anyhoo, that's enough for now. I'm leaving for the PostgreSQL Anniversary Conference early tomorrow morning so need to go and pack...

pgAdmin can be downloaded free of charge from:
This version is a bug fix release containing the following changes:

- Fix serial column detection for 8.1 per Kris Jurka.
- Mask the password when logging the connection string.
- Properly escape single quotes in connection strings.
- Re-arrange the Win32 dependencies so that iconv, libxml2 and wxwidgets are located in $PGADIR/../pgadmin3-deps/.
- Properly enable the redo button in the Query Tool when appropriate, per PromoTrade.
- Add missing files to the Unix tarball, per Andrus - xtra/wxbuild/*, src/utils/precomp.cpp, src/main/pgAdmin3.rc.

We've actually been aware of this for a long time, and have noted the problem a few times on various mailing lists. We've even gone some way to alleviating the problem by showing two query time - if you look in the bottom right hand corner of the query tool you'll see that timings look like: 51243ms + 65343ms.
This is telling you that the query was executed by PostgreSQL, and data transferred to the client in 51.243 seconds, and it was then rendered in the grid in 65.343 seconds.
Edward Di Geronimo Jr recently stepped up and started woring on improving this - specifically to reduce that second figure that tends to throw people, and to provide enhanced copy/paste capabilities. After just three revisions to his original patch it is now looking ready to apply and is showing rendering time consistently reduced by about 75%! In addition, you can now copy data from arbitrary cells, columns, rows or blocks of cells. Nice.
So how does it work? Well, the original code ran the query, and asynchronously populated a wxListView control in a background thread from the result set once the query completed.
The first change in the new code replaces the wxListView control with a wxGrid control. The wxGrid is known to be more light-weight than the wxListView, but is less feature-rich and refined. This meant that special handling was needed to work around quirks such as the control not properly receiving focus when column or row headers were clicked.
The other major change was to create a new, extremely lightweight class (sqlResultTable) to store the query result itself, rather than relying on the grid. The grid is then populated from the result table.
So, the upshot is that the query tool is much faster than it was, and more convenient to copy data from - look out for it in pgAdmin III v1.6!!
And before I forget, many thanks to Ed for his hard work.

Well, I figured it was about time to update the old blog with a new entry for 2006 (Happy New Year btw). A short entry this time - I've just finished a major update of the pgAdmin website.
Nothing spectacular, just:
- an update of the colour scheme to match the current version of pgAdmin
- a re-write of the framework code and CSS
- a whole heap of reorganising of content in order to split some of the excessively long pages down into multiple smaller ones.
- the addition of the 1.4 and development documentation, updated hourly from SVN
Currently it's all in English, but in a week or so once all the typos have been spotted I'll pass it on to the translators.
Anyhoo, check it out at http://www.pgadmin.org. Enjoy.
