1.9.2
415de9a

This release fixes a bug introduced in 1.9.0 with two-stage processing that will lead to crashes. If you are using any 1.9.x version, please upgrade to 1.9.2.

In one case we had some performance problems updating an osm2pgsql database with 1.9.1 due to the PostgreSQL query planning choosing a bad plan. This release contains a workaround for that problem.

We also improved the (experimental) generalizer code a bit:

  • More information is shown in log level 'info', including some timing information.
  • The Lua config run_sql() command now can have either a single SQL statement in the sql field (as before) or a list of SQL commands.
  • For convenience, the Lua config run_sql() command now has an optional transaction field which can be set to true to wrap the SQL commands in BEGIN/COMMIT.
  • The new if_has_rows fields on the run_sql() command can be set to string with an SQL query. If that field is set, the SQL statement(s) in the sql field is only run, if the SQL query returns at least one row.
  • Some performance improvements in low-level code in the generalizer.
