Boundary edges not quite matching up. What to do?

[lalato]

I have a very large number of points of interest... and corresponding lat/long. Was thinking of using geoBoundaries datasets to confirm whether the lat/long data I have is valid. By that I mean... is the lat/long actually within the ADM0 boundaries of the country it's expected to be in.

Unfortunately, I've run into some cases where the geoBoundaries data is just shy of the border. This puts the point of interest outside of the boundaries set by the coordinates in the geoJSON file.

My current solution is to extract the min/max y/x coordinates to at least see if the point is within that larger box.

Apart from reporting these minor issues, is there any other workaround that I could try?

Today I learned about the ST_Buffer function which will allow me to add a small buffer to the country shape that should work fine for my use case.

Still have a lot to learn when it comes to this type of data.
