Description
For create table t23456789012345678901234567890123456789012345678901234567890(g geometry); this ST_EstimatedExtent('public','t23456789012345678901234567890123456789012345678901234567890','g') fails with error 'invalid name syntax'.
It happens in PostGIS 3.5 only. It is fine in 3.4.x.
I think the reason is a change in gserialized_estimated_extent():
char nsp_tbl[NAMEDATALEN]; … snprintf(nsp_tbl, NAMEDATALEN, "\"%s\".\"%s\"", nsp, tbl);
I think nsp_tbl should at least be NAMEDATALEN*2+6 characters long?
