[postgis-users] Changing transaction behaviour in shp2pgsql - summary

[Ben Madin]

Thanks all for the feedback - to summarise :

shp2pgsql - Currently, all output is 'chunked' transactions - changing this behaviour not currently supported. 
 - A patch could be provided to shp2pgsql to do this.
 - The suggestion is a -T switch with options such as single, chunked, no transactions.
 - I'm happy to look at submitting a patch... but it won't be until after I've submitted my thesis ...

The text editor approach is to direct output into a file and find / replace the BEGIN / COMMIT lines.

The on-the-fly alternative is to use a pattern matching program, with two solutions offered :

Using sed (thanks Brent)

    shp2pgsql -s 28350 -W UTF8 \
    /Users/owner/Spatial/country/AUS/WA/MRWA/mrwa_network.shp \
    gis.mrwa_gda94 | sed 's/BEGIN//' | sed 's/COMMIT//' psql australia


Using grep (thanks Steve)

    shp2pgsql ... | grep -v BEGIN | grep -v COMMIT | psql australia

cheers

Ben
