- [debug_pretty_print](/parameters/debug-pretty-print/): debug_pretty_print is the PostgreSQL setting that indents parse and plan tree displays.
- [debug_print_parse](/parameters/debug-print-parse/): debug_print_parse is the PostgreSQL setting that controls whether PostgreSQL logs each query's parse tree.

- [debug_print_raw_parse](/parameters/debug-print-raw-parse/): debug_print_raw_parse — Logs each query's raw parse tree. Observed in PG19 Beta 3; its last measured boot default is off in PG19 Beta 3, with user context. This is a beta-snapshot fact and can change before PostgreSQL 19 GA.

- [log_autoanalyze_min_duration](/parameters/log-autoanalyze-min-duration/): log_autoanalyze_min_duration — Sets the minimum execution time above which analyze actions by autovacuum will be logged. Observed in PG19 Beta 3; its last measured boot default is 10 min in PG19 Beta 3, with sighup context. This is a beta-snapshot fact and can change before PostgreSQL 19 GA.
- [log_autovacuum_min_duration](/parameters/log-autovacuum-min-duration/): log_autovacuum_min_duration is the PostgreSQL setting that defines the minimum execution time above which autovacuum actions will be logged.

- [log_duration](/parameters/log-duration/): log_duration is the PostgreSQL setting that controls whether PostgreSQL logs the duration of each completed SQL statement.
- [log_error_verbosity](/parameters/log-error-verbosity/): log_error_verbosity is the PostgreSQL setting that defines the verbosity of logged messages.
- [log_file_mode](/parameters/log-file-mode/): log_file_mode is the PostgreSQL setting that defines the file permissions for log files.
- [log_filename](/parameters/log-filename/): log_filename is the PostgreSQL setting that defines the file name pattern for log files.
- [log_hostname](/parameters/log-hostname/): log_hostname is the PostgreSQL setting that controls whether PostgreSQL logs the host name in the connection logs.
- [log_line_prefix](/parameters/log-line-prefix/): log_line_prefix is the PostgreSQL setting that controls information prefixed to each log line.
- [log_lock_failures](/parameters/log-lock-failures/): log_lock_failures is the PostgreSQL setting that controls whether PostgreSQL logs lock failures.
- [log_lock_waits](/parameters/log-lock-waits/): log_lock_waits is the PostgreSQL setting that controls whether PostgreSQL logs long lock waits.
- [log_min_duration_sample](/parameters/log-min-duration-sample/): log_min_duration_sample is the PostgreSQL setting that defines the minimum execution time above which a sample of statements will be logged. Sampling is determined by "log_statement_sample_rate".
- [log_min_duration_statement](/parameters/log-min-duration-statement/): Logs every completed statement whose duration reaches a threshold. It is a deterministic slow-query capture control, distinct from sampling and from statement cancellation.
- [log_min_error_statement](/parameters/log-min-error-statement/): log_min_error_statement is the PostgreSQL setting that causes all statements generating error at or above this level to be logged.
- [log_min_messages](/parameters/log-min-messages/): log_min_messages is the PostgreSQL setting that defines the message levels that are logged.
- [log_parameter_max_length](/parameters/log-parameter-max-length/): log_parameter_max_length is the PostgreSQL setting that defines the maximum length in bytes of data logged for bind parameter values when logging statements.
- [log_parameter_max_length_on_error](/parameters/log-parameter-max-length-on-error/): log_parameter_max_length_on_error is the PostgreSQL setting that defines the maximum length in bytes of data logged for bind parameter values when logging statements, on error.
- [log_recovery_conflict_waits](/parameters/log-recovery-conflict-waits/): log_recovery_conflict_waits is the PostgreSQL setting that controls whether PostgreSQL logs standby recovery conflict waits.
- [log_replication_commands](/parameters/log-replication-commands/): log_replication_commands is the PostgreSQL setting that controls whether PostgreSQL logs each replication command.
