PackageDescription	PostgreSQL foreign data wrapper for OGR OGR is the vector half of the GDAL spatial data access library. It allows access to a large number of GIS data formats using a simple C API for data reading and writing. Since OGR exposes a simple table structure and PostgreSQL foreign data wrappers allow access to table structures, the fit seems pretty perfect. . This implementation currently has the following limitations: * Only non-spatial query restrictions are pushed down to the OGR driver. PostgreSQL foreign data wrappers support delegating portions of the SQL query to the underlying data source, in this case OGR. This implementation currently pushes down only non-spatial query restrictions, and only for the small subset of comparison operators (>, <, <=, >=, =) supported by OGR. * Spatial restrictions are not pushed down. OGR can handle basic bounding box restrictions and even (for some drivers) more explicit intersection restrictions, but those are not passed to the OGR driver yet. * OGR connections every time Rather than pooling OGR connections, each query makes (and disposes of) two new ones, which seems to be the largest performance drag at the moment for restricted (small) queries. * All columns are retrieved every time. PostgreSQL foreign data wrappers don't require all columns all the time, and some efficiencies can be gained by only requesting the columns needed to fulfill a query. This would be a minimal efficiency improvement, but can be removed given some development time, since the OGR API supports returning a subset of columns.
