p5-dbd-pg variants to support various pgsql installations

[ehainry@…]

I have postgresql81 installed on my machine and when installing p5-dbd-pg, it tried to install postgresql82. As I don't want to have many different postgresql installations, I edited the portfile (:%s/postgresql82/postgresql81/g did the trick).

I would suggest that there are variants for the different postgresql available (as for p5-dbd-mysql)

something like (not tested this syntax)

variant postgresql81 {
depends_lib-delete port:postgresql82
depends_lib-append port:postgresql81
configure.env-delete  PATH=${prefix}/lib/postgresql82/bin:$env(PATH) \
                        POSTGRES_INCLUDE="${prefix}/include/postgresql82" \
                        POSTGRES_LIB="${prefix}/lib/postgresql82 -lssl"
configure.env-append PATH=${prefix}/lib/postgresql81/bin:$env(PATH) \
                        POSTGRES_INCLUDE="${prefix}/include/postgresql81" \
                        POSTGRES_LIB="${prefix}/lib/postgresql81 -lssl"
}
