#175 Compiling with PostgreSQL Driver fails due to syntax error when checking PostgreSQL version

[David Reagan]

Compiling with the PostgreSQL Driver doesn't work. It fails due to a syntax error when checking PostgreSQL version.

I guess the output of the version command changed syntax.

With an Ubuntu 20.04 based image:

checking for PostgreSQL client version >= 8.1.0... expr: syntax error: unexpected argument '(Ubuntu'
expr: syntax error: unexpected argument '(Ubuntu'
expr: syntax error: unexpected argument '(Ubuntu'
expr: syntax error: unexpected argument '1000000'
expr: syntax error: unexpected argument '8001000'
no
configure: error: Required version of libpq not found

This is in an Ubuntu 20.04 based Docker container.

If I switch to one based on 18.04:

checking for PostgreSQL client version >= 8.1.0... expr: syntax error
expr: syntax error
expr: syntax error
expr: syntax error
expr: syntax error
no
configure: error: Required version of libpq not found

If I drop all the way down to a container based on Ubuntu 16.04, compilation succeeds.

My Dockerfile:

FROM ubuntu:20.04

My c/c++ experience is from a few basic college courses, from around 8 - 10 years ago....

Anyone have any idea where you could adjust the version check?
