Subject: [pgjdbc/pgjdbc] PR #4063: fix: getCharacterStream wraps String in StringReader
Date: Sun, 10 May 2026 06:01:48 +0000
Message-ID: <[email protected]> (raw)

Previously returned new CharArrayReader(value.toCharArray()), which allocates a char[] proportional to the string length (2 * n bytes). StringReader wraps the String directly with no extra allocation.

No benchmark written: the allocation is trivially O(n) and the fix is mechanical. Visible in -prof gc as reduced char[] allocation under any workload that calls getCharacterStream().
