LineString interpolation differs between the front and the back

[flomonster]

Describe the bug

The along function provided by turf give different results than ST_LineInterpolatePoint function provided by postgis

What was tried

• With a simple linestring the results are the same
• With a complex linestring both results are realistic but quite different (80m)
• The length computed by both libraries are the same
• Libraries might not use the same projection space
