As benchmarks show, using libc's string-to-integer conversion is pretty slow. At least part of the reason for that is that strtol[l] have to be more generic than what largely is required inside pg. This patch considerably speeds up int2/int4 input (int8 already was already using hand-rolled code). Most of the existing pg_atoi callers have been converted. But as one requires pg_atoi's custom delimiter functionality, and as it seems likely that there's external pg_atoi users, it seems sensible to just keep pg_atoi around.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
