psql -U postgres

If run with -E flag, it will describe the underlaying queries of the \ commands (cool for learning!).

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*

# Conversão em massa de arquivos shapefiles para geojson usando ogr2ogr
# Para mais informações, veja http://ben.balter.com/2013/06/26/how-to-convert-shapefiles-to-geojson-for-use-on-github/

# Observação: Assumo que você está rodando o script em uma pasta com um ou mais arquivos zipados contendo shapefiles
# e a saída será como geojson com crs:84 SRC (para uso no github ou por aí)

# conversão em geojson
function shp2geojson() {
  ogr2ogr -f GeoJSON -t_srs crs:84 "$1.geojson" "$1.shp"
