comment How to update polygon longitude if negative?
Actually, I'm kind of swimming in circles: at the beginning, I wanted to go grom EPSG:4326 to another latlon/WGS84 with long in 0-360°, but get stuck because +lon_wrap is not supported (see gis.stackexchange.com/questions/79447). In your example i see different projections centered around Pacific, but nothing like a geodetic/WGS84. Would such a projection EPSG code exist?

comment How to update polygon longitude if negative?
Thanks for that, but I still answer the same error message. I replaced X(geometry) with ST_X(geometry): same error message too.

comment How to update polygon longitude if negative?
In principle, I'd agree with you. In this specific case, my problem is the dateline, that remain visible, because the polygons are split around it: once centering my openlyers view on the Pacific, the border of the polygons show the dateline, which I don't want.

comment How to change shapefile longitude from -180 - 180 to 0 - 360?
Yes, simple but perfectly working approach. Thanks! Now, I only need to figure out how to get ride of the vertical line (border between the two dissolved polygons) that remains after the dissolve operation.

by "layer" I meant the layer name. I edit my post in that sense, but the error message is still the same.

Yes, that's what I need (sorry for my typo, I've edited it now). I saw your answer below, the problem is that everything is shifted, including the parts in 0-180 that should not move.
