Hi Erik,<BR>
<BR>
(PostGIS 'listers' please forgive me)<BR>
<BR>
I know this is a bit off-topic but have you tried OpenJump?<BR>

You have easy-going multiple polygons merging... <IMG SRC="cid:1217587053.4315.3.camel@213-190-214-90-cmts01.netmadeira.com" ALIGN="middle" ALT=";-)" BORDER="0"><BR>

As to what Erik asked, I'd also like to know as I've never tried that too ... <IMG SRC="cid:1217587053.4315.4.camel@213-190-214-90-cmts01.netmadeira.com" ALIGN="middle" ALT=":)" BORDER="0"><BR>

<FONT COLOR="#000000">I've converted a shapefile of Europe to PostGIS. I would like to merge all the countries together so that I only have one polygon left, the whole contour of Europe. I have tried ST_Union that gives me no result. I've tried several other functions to no avail. Does anybody know how I should proceed?</FONT><BR>
