Even though it’s a standalone CLI utility, Its still part of Spock repo and I would prefer to keep processing it, so the formatting stays consistent across the codebase.

Merge Risk: 🟠 High · up to Although the PR primarily standardizes formatting and CI checks, it also changes runtime C code and currently leaves unresolved races, stuck pause state, connection leaks, possible data corruption or vacuum hazards, an unbuildable configuration path, and unsafe SQL interpolation.

Inline comments:
In `@include/spock_conflict_stat.h`:
- Line 44: The header is missing the final closing `#endif` for the include-guard
SPOCK_CONFLICT_STAT_H; after the existing closing for the version check (`#endif`
/* PG_VERSION_NUM >= 180000 */) add the matching `#endif` for the initial `#ifndef`
SPOCK_CONFLICT_STAT_H (with an explanatory comment like /* SPOCK_CONFLICT_STAT_H
*/) so the include-guard is properly terminated and the file preprocesses
correctly.
In `@utils/pgindent/README.md`:
- Around line 59-62: Update the README entry that currently references
".github/workflows/pgindent-check.yml" to point to
".github/workflows/spockbench.yml" and note that the pgindent check runs as a
step (pgindent check) inside that workflow; change any wording that says the
workflow file runs "./run-pgindent.sh --check" on PRs to instead state that the
spockbench workflow contains a pgindent-check step which executes the script
against pinned PG versions and fetches typedefs for supported branches so
contributors are not directed to a non-existent workflow file.
In `@utils/pgindent/run-pgindent.sh`:
- Around line 42-44: The current loop uses "curl -sf ... >> \"$TMPFILE\" || echo
...", which only warns on failure and can produce incomplete typedefs.list;
change the failure handling so a failed fetch for a branch causes the script to
exit non‑zero (fail fast) instead of continuing. Update the curl invocation that
references BUILDFARM_URL, branch, and TMPFILE to log an error to stderr with
context (including $branch) and then exit 1 when curl fails, ensuring CI stops
on missing typedefs rather than producing flaky --check results.
- Around line 50-55: The current loop in run-pgindent.sh that appends typedef
names to "$TMPFILE" only extracts single-line declarations via awk '{print $3}',
missing anonymous multi-line typedefs whose names appear on the closing brace
line (e.g., "typedef enum { ... } Name;"). Modify the block that iterates over
the keywords ("typedef struct" "typedef enum" "typedef union") to also search
for closing-brace lines and extract the identifier before the trailing
semicolon: for each match include both the single-line pattern extraction
(existing awk '{print $3}') and an additional grep/sed/awk pipeline that finds
lines containing a '}' followed by a token and ';' and appends that token to
"$TMPFILE" (use the same TMPFILE variable and the same include filters), so
names like SpockConflictType, SpockSaveOriginConflictOption, SpockWorkerStatus,
and SpockWorkerType are captured.

For comments with intentional breaks , can you use /*----- to preserve for readability?
Here we should also indent within the comment though too.

I cited an example, but I think there are places where it is better to preserve the breaks or indentations.
The gen-typedefs.sh script accumulated duplicates on each run because it only appended to typedefs.list. Fixed by: - Uncommenting curl to fetch fresh PostgreSQL typedefs (overwrites file) - Adding sort/uniq to remove any internal duplicates - Cleaning up typedefs.list Sorting allow us to stabilise the content in case a struct or enum has been displaced. This ensures repeated script runs produce consistent, deduplicated output.
…heck Replace the minimal gen-typedefs.sh with a full run-pgindent.sh script that fetches typedef lists from the PostgreSQL buildfarm for PG 16, 17, and 18, merges them with Spock-specific typedefs extracted from the source tree, and runs pgindent on all .c/.h files. PG 15 is excluded because pg_bsd_indent is absent from its source tree. The script supports a --check flag for CI dry-run mode and uses set -euo pipefail with fail-fast error handling on curl failures. It uses absolute paths so it works from any working directory. Add .github/workflows/pgindent.yml: a standalone pull-request workflow that builds pg_bsd_indent from PG 18 inside the existing Docker image and runs ./run-pgindent.sh --check. Rewrite utils/pgindent/README.md with full documentation covering quick start, prerequisites, cross-version typedef rationale, CI integration, and the files list. Name previously anonymous enums: - SpockResolveOption in include/spock_conflict.h - GroupProgressTupDescColumns in include/spock_group.h Regenerate typedefs.list from the merged PG 16-18 buildfarm output.

Improve pgindent infrastructure and code formatting
Cross-version typedef solution
Different PostgreSQL major versions define different structs and enums, causing
pgindent to produce different formatting depending on which PG version's typedefs
are used. This PR solves the problem by fetching typedef lists from the PostgreSQL
buildfarm for all supported branches (PG 16, 17, 18), merging them with
Spock-specific typedefs extracted from the source tree, and deduplicating into a
single
typedefs.list. PG 15 is excluded becausepg_bsd_indentis not presentin its source tree and its typedefs are a subset of PG 16's.
Changes
clean up artifacts (empty lines, comment fragments), and support
--checkmode for CI dry-run
pgindent-check.ymlworkflow.The formatting check now runs inside the existing
spockbench.ymlworkflowafter the docker build step, reusing the PG source tree already in the
container. Skipped for the PG 15 matrix entry
