pgsql: Improve coverage of utils/float.h - Mailing list pgsql-committers

Improve coverage of utils/float.h

check_float4_val() checks after underflow and overflow of values
converted from float8 to float4, but there has never been any regression
tests for that.  This brings the coverage of float.h to 100%.
