[Qgis-user] Saving/Loading styles in Postgis

[Burghardt.Scholle at stadt.wolfsburg.de]

Hi Andreas,

To save the layer styles in a PG table is a cool feature ☺. I have no problems to save the table with a connection based on host/database.

A hint from me: QGIS stores the style-information with the data type “xml”. For me this made problems when exporting / importing this data. By default, the XMLPARSER from postgresql works with the "CONTENT" option. When importing a dump file from the “layer styles”-table you get an error message: “ERROR: invalid XML content”. To prevent this, you need to edit the dump file. Before the insert / copy command to insert the layer styles records you must add the statement “SET xmloption TO DOCUMENT;”.

Regards
Burghardt

Strange. I can see the empty layer_styles table in my public schema. But saving fails. Maybe it fails because my PG connection is based on a service definition and not on host/database?

Hi,
Andreas,  Styles are indeed saved in the public schema, in a table named "layer_styles". I had never created such a table so I assume it's created by QGIS.
Just made a test and rename my current "layer_styles" table. Then I successfully save a new layer style in PG from QGIS 2.16: a new table "layer_styles" has automatically been created in the public schema.

Hi,

I have never used the Saving/Loading of styles in Postgis (see http://docs.qgis.org/2.14/en/docs/user_manual/working_with_vector/vector_properties.html#storing-style-in-a-file-or-a-database)

Do I have to create a special styling table for it to enable this?

Because when I try to save it (QGIS 2.16) I get an error message along the lines that my user may not have permissions to save the style. However, I am trying to save the style with a user that has full administrator rights in Postgis.

In what schema and table are the styles stored? I assume in the public schema. Will QGIS automatically create a styling table or do I have to create one myself?

Thank you for any hints!

Andreas
