Probably the most succinct explanation would be to copy & paste from the terminal...
tjhart=> create table a_line( foo line ); CREATE tjhart=> insert into a_line ( foo ) values( '(0,0), (1,1)' ); ERROR: line not yet implemented tjhart=> select version(); version --------------------------------------------------------------------- PostgreSQL 7.2.1 on powerpc-apple-darwin5.3, compiled by GCC 2.95.2 (1 row) The documentation (datatype-geometric.html) indicates both a 'line' type and an 'lseg' type in the summary table at the top of the page. The same code above using the type 'lseg' in place of 'line' works just fine. Why can I create a table with a column of type 'line' if I can't insert into it? ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
