I develop for the PostGIS project, specifically the raster component. Besides general PostGIS raster development, I also work on the raster2pgsql loader. I also poke at the PostGIS raster driver found in GDAL.

Error when using pgsql2shp You'll want to provide more information before anyone can give an informed answer. What is the output from: SELECT postgis_full_version(); |

Update PostGIS after updating GDAL? Yes. Rebuild PostGIS again as that is always the safest option. If you're running GDAL trunk, things should work. It works far better for my projects than 1.9.x |

Why won't this PostGIS query display in QGIS The error makes sense. I'm guessing DB Manager is only using read-only transactions but nextval() will change the database (increments the sequence). You'll want to remove the nextval() and try again. |

Why does ST_Transform fail? What versions of PostGIS and PROJ.4 are you using? Testing the suggested SRID 32647 works with PostGIS -trunk and PROJ.4 4.8.0 |

What are the advantages/disadvantages of populating a PostGIS database with Raster information? in-db is where the source raster (tile) is stored in PostgreSQL. out-db only stores metadata describing the source raster in PostgreSQL and any functions in PostGIS will call the source raster files as needed. In my testing, out-db is slower than in-db. As to why out-db is slower, my suspicion is that PostgreSQL is able to cache the in-db data in its shared buffers while out-db requires calling the source file every time. |
