Neil Conway be2f825d51 Apply the "nodeAgg" optimization to more of the builtin transition ... functions. This patch optimizes int2_sum(), int4_sum(), float4_accum() and float8_accum() to avoid needing to copy the transition function's state for each input tuple of the aggregate. In an extreme case (e.g. SELECT sum(int2_col) FROM table where table has a single column), it improves performance by about 20%. For more complex queries or tables with wider rows, the relative performance improvement will not be as significant.		21 years ago
