postgis_restore [-v] [-L TOC] [-s schema] dumpfile
The postgis_restore command allows extracting SQL statements to re-create objects found in a custom dump of a PostGIS-enabled database while skipping the PostGIS specific objects.
This is only useful for dumps of databases in which PostGIS was enabled by loading the postgis.sql script. Dumps taken from databases in which PostGIS was enabled via CREATE EXTENSION will not have PostGIS objects in them so can safely be restored directly using pg_restore.
Note that this command only works with dumps using the custom format, which are those crated with pg_dump -Fc.
Usage information is printed when the script is invoked with no arguments.
Create a custom dump from olddb:
pg_dump -Fc olddb > olddb.dump
Create a new database newdb:
PostGIS-enable the new database:
psql -c 'CREATE EXTENSION postgis' newdb
Restore your data:
postgis_restore.pl olddb.dump | psql newdb
