Thread: pgsql: Allow specifying initial and maximum segment sizes for DSA.
Allow specifying initial and maximum segment sizes for DSA. Previously, the DSA segment size always started with 1MB and grew up to DSA_MAX_SEGMENT_SIZE. It was inconvenient in certain scenarios, such as when the caller desired a soft constraint on the total DSA segment size, limiting it to less than 1MB. This commit introduces the capability to specify the initial and maximum DSA segment sizes when creating a DSA area, providing more flexibility and control over memory usage.
