10% drop in code line count in PG 17

While working on a talk, I studied the number of code line changes in each major release, and found PG 17 surprisingly reduced code line count by 10%. To get the code line count, I used /pgtop/src/tools/codelines, which runs: find . -name '*.[chyl]' | xargs cat| wc -l Any ideas on the cause of this decrease? I skimmed the major release notes but didn't see anything obvious. I see removal of support for OpenSSL 1.0.1 and AIX. --------------------------------------------------------------------------- version | reldate | months | relnotes | lines | change | % change ----------+------------+--------+----------+---------+---------+---------- 4.2 | 1994-03-17 | | | 250872 | | 1.0 | 1995-09-05 | 18 | | 172470 | -78402 | -31 1.01 | 1996-02-23 | 6 | | 179463 | 6993 | 4 1.09 | 1996-11-04 | 8 | | 178976 | -487 | 0 6.0 | 1997-01-29 | 3 | | 189399 | 10423 | 5 6.1 | 1997-06-08 | 4 | | 200709 | 11310 | 5 6.2 | 1997-10-02 | 4 | | 225848 | 25139 | 12 6.3 | 1998-03-01 | 5 | | 260809 | 34961 | 15 6.4 | 1998-10-30 | 8 | | 297918 | 37109 | 14 6.5 | 1999-06-09 | 7 | | 331278 | 33360 | 11 7.0 | 2000-05-08 | 11 | | 383270 | 51992 | 15 7.1 | 2001-04-13 | 11 | | 410500 | 27230 | 7 7.2 | 2002-02-04 | 10 | 250 | 394274 | -16226 | -3 7.3 | 2002-11-27 | 10 | 305 | 453282 | 59008 | 14 7.4 | 2003-11-17 | 12 | 263 | 508523 | 55241 | 12 8.0 | 2005-01-19 | 14 | 230 | 654437 | 145914 | 28 8.1 | 2005-11-08 | 10 | 174 | 630422 | -24015 | -3 8.2 | 2006-12-05 | 13 | 215 | 684646 | 54224 | 8 8.3 | 2008-02-04 | 14 | 214 | 762697 | 78051 | 11 8.4 | 2009-07-01 | 17 | 314 | 939098 | 176401 | 23 9.0 | 2010-09-20 | 15 | 237 | 999862 | 60764 | 6 9.1 | 2011-09-12 | 12 | 203 | 1069547 | 69685 | 6 9.2 | 2012-09-10 | 12 | 238 | 1148192 | 78645 | 7 9.3 | 2013-09-09 | 12 | 177 | 1195627 | 47435 | 4 9.4 | 2014-12-18 | 15 | 211 | 1261024 | 65397 | 5 9.5 | 2016-01-07 | 13 | 193 | 1340005 | 78981 | 6 9.6 | 2016-09-29 | 9 | 214 | 1380458 | 40453 | 3 10 | 2017-10-05 | 12 | 189 | 1495196 | 114738 | 8 11 | 2018-10-18 | 12 | 170 | 1562537 | 67341 | 4 12 | 2019-10-03 | 11 | 180 | 1616912 | 54375 | 3 13 | 2020-09-24 | 12 | 178 | 1656030 | 39118 | 2 14 | 2021-09-30 | 12 | 220 | 1779777 | 123747 | 7 15 | 2022-10-13 | 12 | 184 | 1815646 | 35869 | 2 16 | 2023-09-14 | 11 | 206 | 1869401 | 53755 | 2 17 | 2024-09-26 | 12 | 182 | 1673116 | -196285 | -10 18 | 2025-09-25 | 12 | 210 | 1750814 | 77698 | 4 Averages | | 11 | 215 | | | 5.89 -- Bruce Momjian <bruce@momjian.us> https://momjian.us EDB https://enterprisedb.com Do not let urgent matters crowd out time for investment in the future.
