pgPostGIS(
conn,
topology = FALSE,
tiger = FALSE,
sfcgal = FALSE,
raster = FALSE,
display = TRUE,

If exec = TRUE
, returns TRUE
if PostGIS is installed.
## 'exec = FALSE' does not install any extension, but nevertheless
## check for available and installed extensions:
if (FALSE) {
pgPostGIS(con, topology = TRUE, tiger = TRUE, sfcgal = TRUE,
exec = FALSE)
}
