[TinyOWS-users] value out of range for type integer

As the PostgreSQL documentation says: pg_get_serial_sequence returns the name of the 
sequence associated with a column, or NULL if no sequence is associated with the 

So, I suggest a patch for TinyOWS to check for this when--check parameter is issued to ensure that all the layers have a sequence tied with a serial/bigserial column, this includes the OWNED BY NONE case. 

Cheers from México

I have an update and fix for my issue - my workaround was keeping me from opening the table in qgis (as postgis connection not WFS) due to the data type of the primary key (bigint) so I decided to give fixing it the old college try.

After upgrading to 1.0.0rc4 and setting LOG_LEVEL to SQL I noticed that tinyows was calling the postgresql function pg_get_serial_sequence and getting a null result.

This was due to some table juggling hanky panky I'd pulled while updating the data which left the sequence in the ownership by an older table which I'd replaced by renaming it and sticking the update in it's place (a terrible practice, I realize).

I had the sequence specified as the DEFAULT value for the column, but pg_get_serial_sequence acutally returns sequencesOWNED BY table.column which was not the case.

This caused tinyOWS to 'helpfully' fabricate huge numbers for the primary key.

Anyway, after a simple
 ALTER SEQUENCE "my_table_gid_seq" OWNED BY my_table.gid;
command, all fell into place. 

I'm not sure whether this is bug or not, but perhaps it should be more natural for tinyOWS to return an error if the following is true:

	* Column has a NOT NULL constraint
	* No sequence can be found for said column

	* No value was providedFabricating values in the face of these conditions seems unwise.

But I might be missing something.

Anyway, just thought I'd throw this out there in case anybody ever stumbles onto this thread with a similar issue.

Hi Olivier,
