comment Coordinates conversion doubt
Thank you Andre. I think you refer to the "Set Project CRS from layer", which is a nice solution for me. However I still need to develop some lookup functionality via a python routine or shell script, so I'll keep digging. Thank you again!

comment Coordinates conversion doubt
nice one thanks :) This is the command that I issue to manually enter EPSG:900113 coordinates and get EPSG:4326 coordinates: cs2cs +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +units=m +k=1.0 +nadgrids=@null +no_defs Then I enter "-7148300 -3688500 " without quotes and get: 64d12'51.377"W 31d25'41.939"S 0.000

comment How to reproject this vector layer?
Thank you Andre. The extent of coordinates of the picture is aproximately -61.50, -29.40 to -65.90, -35.20. I don't know how to determine a coordinate based on the linestring field of a database... The little square of the upper center is at -31°25′ -64°11′.

Thank you. Indeed, the units are set to meters. This is the CRS definition (EPSG:3857): +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs

Thanks, but then why on osm extracts is specified EPSG:4326?

comment How to reproject this vector layer?
Another solution would be distort visually the green line layer, as the QGIS plugin Affine is not of much help here in this case... but cannot find such a tool in any open source GIS.

comment How to query osm data served by geoserver?
Yes, but I think it's not what I need in this case, as the features are all in shapefiles.
