PostgreSQL syntax error: LOCK IN SHARE MODE when running Category
Closed, ResolvedPublic


Author: darkcircle.0426

This patch is for getting rid of "LOCK IN SHARE MODE" related warning message.

Warning: pg_query() []: Query failed: ERROR: syntax error at or near "LOCK" LINE 1: ... in ${MEDIAWIKI_HOME}/includes/db/DatabasePostgres.php on line 254 when category page is called.

as below commit message
"LOCK IN SHARE MODE" is a MySQL extension not supported by another SQL Engine.

so I suggest very simple patch for eliminating this issue.

Version: 1.22.0
Severity: normal

I think PostgreSQL has "FOR SHARE" SELECT option. By then, issues listed in bug 47055 apply.

Hi Seong-ho Cho,

I tried to apply your patch, but unfortunately it did not apply cleanly. To submit a patch, you can now also use the on-line patch uploader at . Of course, you can also submit it directly using git.

Was already fixed with bug 39635, thats why the provided patch cannot apply to current master.
