Tom Lane 22d9ddbb35 Fix planner to make a reasonable assumption about the amount of memory space ... used by array_agg(), string_agg(), and similar aggregate functions that use "internal" as their transition datatype. The previous coding thought this took *no* extra space, since "internal" is pass-by-value; but actually these aggregates typically consume a great deal of space. Per bug #5608 from Itagaki Takahiro, and fix suggestion from Hitoshi Harada. Back-patch to 8.4, where array_agg was introduced.		16 years ago
